+Callback functions for environment variables:
+---------------------------------------------
+
+For some environment variables, the behavior of u-boot needs to change
+when their values are changed. This functionailty allows functions to
+be associated with arbitrary variables. On creation, overwrite, or
+deletion, the callback will provide the opportunity for some side
+effect to happen or for the change to be rejected.
+
+The callbacks are named and associated with a function using the
+U_BOOT_ENV_CALLBACK macro in your board or driver code.
+
+These callbacks are associated with variables in one of two ways. The
+static list can be added to by defining CONFIG_ENV_CALLBACK_LIST_STATIC
+in the board configuration to a string that defines a list of
+associations. The list must be in the following format:
+
+ entry = variable_name[:callback_name]
+ list = entry[,list]
+
+If the callback name is not specified, then the callback is deleted.
+Spaces are also allowed anywhere in the list.
+
+Callbacks can also be associated by defining the ".callbacks" variable
+with the same list format above. Any association in ".callbacks" will
+override any association in the static list. You can define
+CONFIG_ENV_CALLBACK_LIST_DEFAULT to a list (string) to define the
+".callbacks" envirnoment variable in the default or embedded environment.

+A3M071 board support
+------------------------------------------------------------------------
+
+
+SPL NOR flash support:
+----------------------
+To boot fast into the OS (Linux), this board port integrates the SPL
+framework. This means, that a special, stripped-down version of
+U-Boot runs in the beginning. In the case of the A3M071 board, this
+SPL U-Boot version is less than 16 KiB big. This SPL U-Boot can either
+boot the OS (Linux) or a "real", full-blown U-Boot. This detection
+on whether to boot Linux or U-Boot is done by using the "boot_os"
+environment variable. If "boot_os" is set to "yes", Linux will be
+loaded and booted from the SPL U-Boot version. Otherwise, the
+full-blown U-Boot version will be loaded and run.
+
+Enabling Linux booting:
+-----------------------
+From U-Boot:
+=> setenv boot_os yes
+=> saveenv
+
+From Linux:
+$ fw_setenv boot_os yes
+
+Enabling U-Boot booting:
+------------------------
+From U-Boot:
+=> setenv boot_os no
+=> saveenv
+
+From Linux:
+$ fw_setenv boot_os no
+
+
+Preparing Linux image(s) for booting from SPL U-Boot:
+-----------------------------------------------------
+To boot the Linux kernel from the SPL, the DT blob (fdt) needs to get
+prepard/patched first. U-Boot usually inserts some dynamic values into
+the DT binary (blob), e.g. autodetected memory size, MAC addresses,
+clocks speeds etc. To generate this patched DT blob, you can use
+the following command:
+
+1. Load fdt blob to SDRAM:
+=> tftp 1800000 a3m071/a3m071.dtb
+
+2. Set bootargs as desired for Linux booting (e.g. flash_mtd):
+=> run mtdargs addip2 addtty
+
+3. Use "fdt" commands to patch the DT blob:
+=> fdt addr 1800000
+=> fdt boardsetup
+=> fdt chosen
+
+4. Display patched DT blob (optional):
+=> fdt print
+
+5. Save fdt to NOR flash:
+=> erase fc060000 fc07ffff
+=> cp.b 1800000 fc060000 10000
+
+All this can be integrated into an environment command:
+=> setenv upd_fdt 'tftp 1800000 a3m071/a3m071.dtb;run mtdargs addip2 addtty; \
+ fdt addr 1800000;fdt boardsetup;erase fc060000 fc07ffff; \
+ cp.b 1800000 fc060000 10000'
+=> saveenv
+
+After this, only "run upd_fdt" needs to get called to load, patch
+and save the DT blob into NOR flash.
+
+Additionally, the Linux kernel image has to be saved uncompressed in
+its uImage file (and not gzip compressed). This can be done with this
+command:
+
+$ mkimage -A ppc -O linux -T kernel -C none -a 0 -e 0 \
+ -n "Linux Kernel Image" -d vmlinux.bin uImage.uncompressed

+/*
+ * This file handles the board muxing between the Fman Ethernet MACs and
+ * the RGMII/SGMII/XGMII PHYs on a Freescale P5040 "Super Hydra" reference
+ * board. The RGMII PHYs are the two on-board 1Gb ports. The SGMII PHYs are
+ * provided by the standard Freescale four-port SGMII riser card. The 10Gb
+ * XGMII PHYs are provided via the XAUI riser card. The P5040 has 2 FMans
+ * and 5 1G interfaces and 10G interface per FMan. Based on the options in
+ * the RCW, we could have upto 3 SGMII cards and 1 XAUI card at a time.
+ *
+ * Muxing is handled via the PIXIS BRDCFG1 register. The EMI1 bits control
+ * muxing among the RGMII PHYs and the SGMII PHYs. The value for RGMII is
+ * always the same (0). The value for SGMII depends on which slot the riser is
+ * inserted in. The EMI2 bits control muxing for the the XGMII. Like SGMII,
+ * the value is based on which slot the XAUI is inserted in.
+ *
+ * The SERDES configuration is used to determine where the SGMII and XAUI cards
+ * exist, and also which Fman's MACs are routed to which PHYs. So for a given
+ * Fman MAC, there is one and only PHY it connects to. MACs cannot be routed
+ * to PHYs dynamically.
+ *
+ *
+ * This file also updates the device tree in three ways:
+ *
+ * 1) The status of each virtual MDIO node that is referenced by an Ethernet
+ * node is set to "okay".
+ *
+ * 2) The phy-handle property of each active Ethernet MAC node is set to the
+ * appropriate PHY node.
+ *
+ * 3) The "mux value" for each virtual MDIO node is set to the correct value,
+ * if necessary. Some virtual MDIO nodes do not have configurable mux
+ * values, so those values are hard-coded in the DTS. On the HYDRA board,
+ * the virtual MDIO node for the SGMII card needs to be updated.
+ *
+ * For all this to work, the device tree needs to have the following:
+ *
+ * 1) An alias for each PHY node that an Ethernet node could be routed to.
+ *
+ * 2) An alias for each real and virtual MDIO node that is disabled by default
+ * and might need to be enabled, and also might need to have its mux-value
+ * updated.

+Introduction:
+=============
+This document describes the GPT partition table format and usage of
+the gpt command in u-boot.
+
+
+UUID introduction:
+====================
+
+GPT for marking disks/partitions is using the UUID. It is supposed to be a
+globally unique value. A UUID is a 16-byte (128-bit) number. The number of
+theoretically possible UUIDs is therefore about 3 x 10^38.
+More often UUID is displayed as 32 hexadecimal digits, in 5 groups,
+separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters
+(32 digits and 4 hyphens)
+
+For instance, GUID of Linux data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
+
+Historically there are 5 methods to generate this number. The oldest one is
+combining machine's MAC address and timer (epoch) value.
+
+Successive versions are using MD5 hash, random numbers and SHA-1 hash. All major
+OSes and programming languages are providing libraries to compute UUID (e.g.
+uuid command line tool).
+
+GPT brief explanation:
+======================
+
+ Layout:
+ -------
+
+ --------------------------------------------------
+ LBA 0 |Protective MBR |
+ ----------------------------------------------------------
+ LBA 1 |Primary GPT Header | Primary
+ -------------------------------------------------- GPT
+ LBA 2 |Entry 1|Entry 2| Entry 3| Entry 4|
+ --------------------------------------------------
+ LBA 3 |Entries 5 - 128 |
+ | |
+ | |
+ ----------------------------------------------------------
+ LBA 34 |Partition 1 |
+ | |
+ -----------------------------------
+ |Partition 2 |
+ | |
+ -----------------------------------
+ |Partition n |
+ | |
+ ----------------------------------------------------------
+ LBA -34 |Entry 1|Entry 2| Entry 3| Entry 4| Secondary
+ -------------------------------------------------- (bkp)
+ LBA -33 |Entries 5 - 128 | GPT
+ | |
+ | |
+ LBA -2 | |
+ --------------------------------------------------
+ LBA -1 |Secondary GPT Header |
+ ----------------------------------------------------------
+
+
+For a legacy reasons, GPT's LBA 0 sector has a MBR structure. It is called
+"protective MBR".
+Its first partition entry ID has 0xEE value, and disk software, which is not
+handling the GPT sees it as a storage device without free space.
+
+It is possible to define 128 linearly placed partition entries.
+
+"LBA -1" means the last addressable block (in the mmc subsystem:
+"dev_desc->lba - 1")
+
+Primary/Secondary GPT header:
+----------------------------
+Offset Size Description
+
+0 8 B Signature ("EFI PART", 45 46 49 20 50 41 52 54)
+8 4 B Revision (For version 1.0, the value is 00 00 01 00)
+12 4 B Header size (in bytes, usually 5C 00 00 00 meaning 92 bytes)
+16 4 B CRC32 of header (0 to header size), with this field zeroed
+ during calculation
+20 4 B Reserved (ZERO);
+24 8 B Current LBA (location of this header copy)
+32 8 B Backup LBA (location of the other header copy)
+40 8 B First usable LBA for partitions (primary partition table last
+ LBA + 1)
+48 8 B Last usable LBA (secondary partition table first LBA - 1)
+56 16 B Disk GUID (also referred as UUID on UNIXes)
+72 8 B Partition entries starting LBA (always 2 in primary copy)
+80 4 B Number of partition entries
+84 4 B Size of a partition entry (usually 128)
+88 4 B CRC32 of partition array
+92 * Reserved; must be ZERO (420 bytes for a 512-byte LBA)
+
+TOTAL: 512 B
+
+
+
+IMPORTANT:
+
+GPT headers and partition entries are protected by CRC32 (the POSIX CRC32).
+
+Primary GPT header and Secondary GPT header have swapped values of "Current LBA"
+and "Backup LBA" and therefore different CRC32 check-sum.
+
+CRC32 for GPT headers (field "CRC of header") are calculated up till
+"Header size" (92), NOT 512 bytes.
+
+CRC32 for partition entries (field "CRC32 of partition array") is calculated for
+the whole array entry ( Number_of_partition_entries *
+sizeof(partition_entry_size (usually 128)))
+
+Observe, how Secondary GPT is placed in the memory. It is NOT a mirror reflect
+of the Primary.
+
+
+ Partition Entry Format:
+ ----------------------
+ Offset Size Description
+
+ 0 16 B Partition type GUID
+ 16 16 B Unique partition GUID
+ 32 8 B First LBA (Little Endian)
+ 40 8 B Last LBA (inclusive)
+ 48 8 B Attribute flags [+]
+ 56 72 B Partition name (text)
+
+ Attribute flags:
+ Bit 0 - System partition
+ Bit 60 - Read-only
+ Bit 62 - Hidden
+ Bit 63 - Not mount
+
+
+Creating GPT partitions in U-Boot:
+==============
+
+To restore GUID partition table one needs to:
+1. Define partition layout in the environment.
+ Format of partitions layout:
+ "partitions=uuid_disk=...;name=u-boot,size=60MiB,uuid=...;
+ name=kernel,size=60MiB,uuid=...;"
+ or
+ "partitions=uuid_disk=${uuid_gpt_disk};name=${uboot_name},
+ size=${uboot_size},uuid=${uboot_uuid};"
+
+ Fields 'name', 'size' and 'uuid' are mandatory for every partition.
+ The field 'start' is optional.
+
+2. Define 'CONFIG_EFI_PARTITION' and 'CONFIG_CMD_GPT'
+
+2. From u-boot prompt type:
+ gpt write mmc 0 $partitions
+
+
+Useful info:
+============
+
+Two programs, namely: 'fdisk' and 'parted' are recommended to work with GPT
+recovery. Parted is able to handle GUID partitions. Unfortunately the 'fdisk'
+hasn't got such ability.
+Please, pay attention at -l switch for parted.
+
+"uuid" program is recommended to generate UUID string. Moreover it can decode
+(-d switch) passed in UUID string. It can be used to generate partitions UUID
+passed to u-boot environment variables.

+ * This is a GPIO driver for Intel ICH6 and later. The x86 GPIOs are accessed
+ * through the PCI bus. Each PCI device has 256 bytes of configuration space,
+ * consisting of a standard header and a device-specific set of registers. PCI
+ * bus 0, device 31, function 0 gives us access to the chipset GPIOs (among
+ * other things). Within the PCI configuration space, the GPIOBASE register
+ * tells us where in the device's I/O region we can find more registers to
+ * actually access the GPIOs.
+ *
+ * PCI bus/device/function 0:1f:0 => PCI config registers
+ * PCI config register "GPIOBASE"
+ * PCI I/O space + [GPIOBASE] => start of GPIO registers
+ * GPIO registers => gpio pin function, direction, value
+ *
+ *
+ * Danger Will Robinson! Bank 0 (GPIOs 0-31) seems to be fairly stable. Most
+ * ICH versions have more, but the decoding the matrix that describes them is
+ * absurdly complex and constantly changing. We'll provide Bank 1 and Bank 2,
+ * but they will ONLY work for certain unspecified chipsets because the offset
+ * from GPIOBASE changes randomly. Even then, many GPIOs are unimplemented or
+ * reserved or subject to arcane restrictions.

+ * Inventra (Multipoint) Dual-Role Controller Driver for Linux.
+ *
+ * This consists of a Host Controller Driver (HCD) and a peripheral
+ * controller driver implementing the "Gadget" API; OTG support is
+ * in the works. These are normal Linux-USB controller drivers which
+ * use IRQs and have no dedicated thread.
+ *
+ * This version of the driver has only been used with products from
+ * Texas Instruments. Those products integrate the Inventra logic
+ * with other DMA, IRQ, and bus modules, as well as other logic that
+ * needs to be reflected in this driver.
+ *
+ *
+ * NOTE: the original Mentor code here was pretty much a collection
+ * of mechanisms that don't seem to have been fully integrated/working
+ * for *any* Linux kernel version. This version aims at Linux 2.6.now,
+ * Key open issues include:
+ *
+ * - Lack of host-side transaction scheduling, for all transfer types.
+ * The hardware doesn't do it; instead, software must.
+ *
+ * This is not an issue for OTG devices that don't support external
+ * hubs, but for more "normal" USB hosts it's a user issue that the
+ * "multipoint" support doesn't scale in the expected ways. That
+ * includes DaVinci EVM in a common non-OTG mode.
+ *
+ * * Control and bulk use dedicated endpoints, and there's as
+ * yet no mechanism to either (a) reclaim the hardware when
+ * peripherals are NAKing, which gets complicated with bulk
+ * endpoints, or (b) use more than a single bulk endpoint in
+ * each direction.
+ *
+ * RESULT: one device may be perceived as blocking another one.
+ *
+ * * Interrupt and isochronous will dynamically allocate endpoint
+ * hardware, but (a) there's no record keeping for bandwidth;
+ * (b) in the common case that few endpoints are available, there
+ * is no mechanism to reuse endpoints to talk to multiple devices.
+ *
+ * RESULT: At one extreme, bandwidth can be overcommitted in
+ * some hardware configurations, no faults will be reported.
+ * At the other extreme, the bandwidth capabilities which do
+ * exist tend to be severely undercommitted. You can't yet hook
+ * up both a keyboard and a mouse to an external USB hub.
+ */
+
+/*
+ * This gets many kinds of configuration information:
+ * - Kconfig for everything user-configurable
+ * - platform_device for addressing, irq, and platform_data
+ * - platform_data is mostly for board-specific informarion
+ * (plus recentrly, SOC or family details)
+ *
+ * Most of the conditional compilation will (someday) vanish.

+/* MUSB PERIPHERAL status 3-mar-2006:
+ *
+ * - EP0 seems solid. It passes both USBCV and usbtest control cases.
+ * Minor glitches:
+ *
+ * + remote wakeup to Linux hosts work, but saw USBCV failures;
+ * in one test run (operator error?)
+ * + endpoint halt tests -- in both usbtest and usbcv -- seem
+ * to break when dma is enabled ... is something wrongly
+ * clearing SENDSTALL?
+ *
+ * - Mass storage behaved ok when last tested. Network traffic patterns
+ * (with lots of short transfers etc) need retesting; they turn up the
+ * worst cases of the DMA, since short packets are typical but are not
+ * required.
+ *
+ * - TX/IN
+ * + both pio and dma behave in with network and g_zero tests
+ * + no cppi throughput issues other than no-hw-queueing
+ * + failed with FLAT_REG (DaVinci)
+ * + seems to behave with double buffering, PIO -and- CPPI
+ * + with gadgetfs + AIO, requests got lost?
+ *
+ * - RX/OUT
+ * + both pio and dma behave in with network and g_zero tests
+ * + dma is slow in typical case (short_not_ok is clear)
+ * + double buffering ok with PIO
+ * + double buffering *FAILS* with CPPI, wrong data bytes sometimes
+ * + request lossage observed with gadgetfs
+ *
+ * - ISO not tested ... might work, but only weakly isochronous
+ *
+ * - Gadget driver disabling of softconnect during bind() is ignored; so
+ * drivers can't hold off host requests until userspace is ready.
+ * (Workaround: they can turn it off later.)
+ *
+ * - PORTABILITY (assumes PIO works):
+ * + DaVinci, basically works with cppi dma
+ * + OMAP 2430, ditto with mentor dma
+ * + TUSB 6010, platform-specific dma in the works

+ *
+ * - There's still lots of partial code duplication for fault paths, so
+ * they aren't handled as consistently as they need to be.
+ *
+ * - PIO mostly behaved when last tested.
+ * + including ep0, with all usbtest cases 9, 10
+ * + usbtest 14 (ep0out) doesn't seem to run at all
+ * + double buffered OUT/TX endpoints saw stalls(!) with certain usbtest
+ * configurations, but otherwise double buffering passes basic tests.
+ * + for 2.6.N, for N > ~10, needs API changes for hcd framework.
+ *
+ * - DMA (CPPI) ... partially behaves, not currently recommended
+ * + about 1/15 the speed of typical EHCI implementations (PCI)
+ * + RX, all too often reqpkt seems to misbehave after tx
+ * + TX, no known issues (other than evident silicon issue)
+ *
+ * - DMA (Mentor/OMAP) ...has at least toggle update problems
+ *
+ * - [23-feb-2009] minimal traffic scheduling to avoid bulk RX packet
+ * starvation ... nothing yet for TX, interrupt, or bulk.
+ *
+ * - Not tested with HNP, but some SRP paths seem to behave.
+ *
+ * NOTE 24-August-2006:
+ *
+ * - Bulk traffic finally uses both sides of hardware ep1, freeing up an
+ * extra endpoint for periodic use enabling hub + keybd + mouse. That
+ * mostly works, except that with "usbnet" it's easy to trigger cases
+ * with "ping" where RX loses. (a) ping to davinci, even "ping -f",
+ * fine; but (b) ping _from_ davinci, even "ping -c 1", ICMP RX loses
+ * although ARP RX wins. (That test was done with a full speed link.)
+ */

+/*
+ * NOTE on endpoint usage:
+ *
+ * CONTROL transfers all go through ep0. BULK ones go through dedicated IN
+ * and OUT endpoints ... hardware is dedicated for those "async" queue(s).
+ * (Yes, bulk _could_ use more of the endpoints than that, and would even
+ * benefit from it.)
+ *
+ * INTERUPPT and ISOCHRONOUS transfers are scheduled to the other endpoints.
+ * So far that scheduling is both dumb and optimistic: the endpoint will be
+ * "claimed" until its software queue is no longer refilled. No multiplexing
+ * of transfers between endpoints, or anything clever.
