Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+
+The ELAN-104NC has up to 8 Mibyte of Intel StrataFlash (28F320/28F640) in x16
+mode. This drivers uses the CFI probe and Intel Extended Command Set drivers.
+
+The flash is accessed as follows:
+
+ 32 kbyte memory window at 0xb0000-0xb7fff
+
+ 16 bit I/O port (0x22) for some sort of paging.
+
+The single flash device is divided into 3 partition which appear as separate
+MTD devices.
+
+Linux thinks that the I/O port is used by the PIC and hence check_region() will
+always fail. So we don't do it. I just hope it doesn't break anything.

+
+ Octagon 5066 MTD Driver.
+
+ The Octagon 5066 is a SBC based on AMD's 586-WB running at 133 MHZ. It
+ comes with a builtin AMD 29F016 flash chip and a socketed EEPROM that
+ is replacable by flash. Both units are mapped through a multiplexer
+ into a 32k memory window at 0xe8000. The control register for the
+ multiplexing unit is located at IO 0x208 with a bit map of
+ 0-5 Page Selection in 32k increments
+ 6-7 Device selection:
+ 00 SSD off
+ 01 SSD 0 (Socket)
+ 10 SSD 1 (Flash chip)
+ 11 undefined
+
+ On each SSD, the first 128k is reserved for use by the bios
+ (actually it IS the bios..) This only matters if you are booting off the
+ flash, you must not put a file system starting there.
+
+ The driver tries to do a detection algorithm to guess what sort of devices
+ are plugged into the sockets.

+The SBC-MediaGX / SBC-GXx has up to 16 MiB of
+Intel StrataFlash (28F320/28F640) in x8 mode.
+
+This driver uses the CFI probe and Intel Extended Command Set drivers.
+
+The flash is accessed as follows:
+
+ 16 KiB memory window at 0xdc000-0xdffff
+
+ Two IO address locations for paging
+
+ 0x258
+ bit 0-7: address bit 14-21
+ 0x259
+ bit 0-1: address bit 22-23
+ bit 7: 0 - reset/powered down
+ 1 - device enabled
+
+The single flash device is divided into 3 partition which appear as
+separate MTD devices.

+** (that's what 0x8400000 binary's ought to be). But this is the highest
+** order address line on the raw flash devices themselves!!
+** This causes the top HALF of the flash to be accessed first. Beyond
+** the physical limits of the flash, the flash chip aliases over (to
+** 0x880000 which causes the bottom half to be accessed. This splits the
+** flash into two and inverts it! If you then try to access this from another
+** program that does NOT do this insanity, then you *will* access the
+** first half of the flash, but not find what you expect there. That
+** stuff is in the *second* half! Similarly, the address used by the
+** BIOS for the second FLASH bank is also quite a bad choice.
+** If REPROGRAM_PAR is defined below (the default), then this driver will
+** choose more useful addresses for the FLASH banks by reprogramming the
+** responsible PARxx registers in the SC520's MMCR region. This will
+** cause the settings to be incompatible with the BIOS's settings, which
+** shouldn't be a problem since you are running Linux, (i.e. the BIOS is
+** not much use anyway). However, if you need to be compatible with

+ * MTD map driver for BIOS Flash on Intel SCB2 boards
+ * $Id: scb2_flash.c,v 1.11 2004/11/28 09:40:40 dwmw2 Exp $
+ * Copyright (C) 2002 Sun Microsystems, Inc.
+ * Tim Hockin <thockin@sun.com>
+ *
+ * A few notes on this MTD map:
+ *
+ * This was developed with a small number of SCB2 boards to test on.
+ * Hopefully, Intel has not introducted too many unaccounted variables in the
+ * making of this board.
+ *
+ * The BIOS marks its own memory region as 'reserved' in the e820 map. We
+ * try to request it here, but if it fails, we carry on anyway.
+ *
+ * This is how the chip is attached, so said the schematic:
+ * * a 4 MiB (32 Mib) 16 bit chip
+ * * a 1 MiB memory region
+ * * A20 and A21 pulled up
+ * * D8-D15 ignored
+ * What this means is that, while we are addressing bytes linearly, we are
+ * really addressing words, and discarding the other byte. This means that
+ * the chip MUST BE at least 2 MiB. This also means that every block is
+ * actually half as big as the chip reports. It also means that accesses of
+ * logical address 0 hit higher-address sections of the chip, not physical 0.
+ * One can only hope that these 4MiB x16 chips were a lot cheaper than 1MiB x8
+ * chips.
+ *
+ * This driver assumes the chip is not write-protected by an external signal.
+ * As of the this writing, that is true, but may change, just to spite me.
+ *
+ * The actual BIOS layout has been mostly reverse engineered. Intel BIOS
+ * updates for this board include 10 related (*.bio - &.bi9) binary files and
+ * another separate (*.bbo) binary file. The 10 files are 64k of data + a
+ * small header. If the headers are stripped off, the 10 64k files can be
+ * concatenated into a 640k image. This is your BIOS image, proper. The
+ * separate .bbo file also has a small header. It is the 'Boot Block'
+ * recovery BIOS. Once the header is stripped, no further prep is needed.
+ * As best I can tell, the BIOS is arranged as such:
+ * offset 0x00000 to 0x4ffff (320k): unknown - SCSI BIOS, etc?
+ * offset 0x50000 to 0xeffff (640k): BIOS proper
+ * offset 0xf0000 ty 0xfffff (64k): Boot Block region
+ *
+ * Intel's BIOS update program flashes the BIOS and Boot Block in separate
+ * steps. Probably a wise thing to do.

+ Tempustech VMAX SBC301 MTD Driver.
+
+ The VMAx 301 is a SBC based on . It
+ comes with three builtin AMD 29F016B flash chips and a socket for SRAM or
+ more flash. Each unit has it's own 8k mapping into a settable region
+ (0xD8000). There are two 8k mappings for each MTD, the first is always set
+ to the lower 8k of the device the second is paged. Writing a 16 bit page
+ value to anywhere in the first 8k will cause the second 8k to page around.
+
+ To boot the device a bios extension must be installed into the first 8k
+ of flash that is smart enough to copy itself down, page in the rest of
+ itself and begin executing.
