+1. Android
+==========
+
+Android (www.android.com) is an open source operating system for mobile devices.
+This document describes configurations needed to run the Android framework on
+top of the Linux kernel.
+
+To see a working defconfig look at msm_defconfig or goldfish_defconfig
+which can be found at http://android.git.kernel.org in kernel/common.git
+and kernel/msm.git
+
+
+1.1 Required enabled config options
+-----------------------------------
+After building a standard defconfig, ensure that these options are enabled in
+your .config or defconfig if they are not already. Based off the msm_defconfig.
+You should keep the rest of the default options enabled in the defconfig
+unless you know what you are doing.

default value of '20' it means that if the CPU usage needs to be below
20% between samples to have the frequency decreased.
+
+2.6 Interactive
+---------------
+
+The CPUfreq governor "interactive" is designed for latency-sensitive,
+interactive workloads. This governor sets the CPU speed depending on
+usage, similar to "ondemand" and "conservative" governors. However,
+the governor is more aggressive about scaling the CPU speed up in
+response to CPU-intensive activity.
+
+Sampling the CPU load every X ms can lead to under-powering the CPU
+for X ms, leading to dropped frames, stuttering UI, etc. Instead of
+sampling the cpu at a specified rate, the interactive governor will
+check whether to scale the cpu frequency up soon after coming out of
+idle. When the cpu comes out of idle, a timer is configured to fire
+within 1-2 ticks. If the cpu is very busy between exiting idle and
+when the timer fires then we assume the cpu is underpowered and ramp
+to MAX speed.
+
+If the cpu was not sufficiently busy to immediately ramp to MAX speed,
+then governor evaluates the cpu load since the last speed adjustment,
+choosing th highest value between that longer-term load or the
+short-term load since idle exit to determine the cpu speed to ramp to.
+
+The tuneable value for this governor are:
+
+min_sample_time: The minimum amount of time to spend at the current
+frequency before ramping down. This is to ensure that the governor has
+seen enough historic cpu load data to determine the appropriate
+workload. Default is 80000 uS.
+
+go_maxspeed_load: The CPU load at which to ramp to max speed. Default
+is 85.

+ The memory driver provides two character devices, mem and kmem, which

+ the addresses correspond to the kernel's virtual address space rather
+ than physical memory. These devices are standard parts of a Linux

+ * For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and

+ * with a oom_adj value of 8 or higher when the free memory drops below 4096 pages
+ * and kill processes with a oom_adj value of 0 or higher when the free memory
+ * drops below 1024 pages.
+ *
+ * The driver considers memory used for caches to be free, but if a large
+ * percentage of the cached memory is locked this can be very inaccurate
+ * and processes may not get killed until the normal oom killer is triggered.

+ select YAFFS_YAFFS2
+ help
+ YAFFS2, or Yet Another Flash Filing System, is a filing system
+ optimised for NAND Flash chips.
+
+ To compile the YAFFS2 file system support as a module, choose M
+ here: the module will be called yaffs2.
+
+ If unsure, say N.
+
+ Further information on YAFFS2 is available at
+ <http://www.aleph1.co.uk/yaffs/>.
+
+config YAFFS_YAFFS1
+ bool "512 byte / page devices"
+ depends on YAFFS_FS
+ default y
+ help
+ Enable YAFFS1 support -- yaffs for 512 byte / page devices
+
+ Not needed for 2K-page devices.
+
+ If unsure, say Y.
+
+config YAFFS_9BYTE_TAGS
+ bool "Use older-style on-NAND data format with pageStatus byte"
+ depends on YAFFS_YAFFS1
+ default n
+ help
+
+ Older-style on-NAND data format has a "pageStatus" byte to record
+ chunk/page state. This byte is zero when the page is discarded.
+ Choose this option if you have existing on-NAND data using this
+ format that you need to continue to support. New data written
+ also uses the older-style format. Note: Use of this option
+ generally requires that MTD's oob layout be adjusted to use the
+ older-style format. See notes on tags formats and MTD versions
+ in yaffs_mtdif1.c.
+
+ If unsure, say N.
+
+config YAFFS_DOES_ECC
+ bool "Lets Yaffs do its own ECC"
+ depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
+ default n
+ help
+ This enables Yaffs to use its own ECC functions instead of using
+ the ones from the generic MTD-NAND driver.
+
+ If unsure, say N.
+
+config YAFFS_ECC_WRONG_ORDER
+ bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
+ depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
+ default n
+ help
+ This makes yaffs_ecc.c use the same ecc byte order as Steven
+ Hill's nand_ecc.c. If not set, then you get the same ecc byte
+ order as SmartMedia.
+
+ If unsure, say N.
+
+config YAFFS_YAFFS2
+ bool "2048 byte (or larger) / page devices"
+ depends on YAFFS_FS
+ default y
+ help
+ Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices
+
+ If unsure, say Y.
+
+config YAFFS_AUTO_YAFFS2
+ bool "Autoselect yaffs2 format"
+ depends on YAFFS_YAFFS2
+ default y
+ help
+ Without this, you need to explicitely use yaffs2 as the file
+ system type. With this, you can say "yaffs" and yaffs or yaffs2
+ will be used depending on the device page size (yaffs on
+ 512-byte page devices, yaffs2 on 2K page devices).
+
+ If unsure, say Y.
+
+config YAFFS_DISABLE_TAGS_ECC
+ bool "Disable YAFFS from doing ECC on tags by default"
+ depends on YAFFS_FS && YAFFS_YAFFS2
+ default n
+ help
+ This defaults Yaffs to using its own ECC calculations on tags instead of
+ just relying on the MTD.
+ This behavior can also be overridden with tags_ecc_on and
+ tags_ecc_off mount options.
+
+ If unsure, say N.
+
+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
+ bool "Force chunk erase check"
+ depends on YAFFS_FS
+ default n
+ help
+ Normally YAFFS only checks chunks before writing until an erased
+ chunk is found. This helps to detect any partially written
+ chunks that might have happened due to power loss.
+
+ Enabling this forces on the test that chunks are erased in flash
+ before writing to them. This takes more time but is potentially
+ a bit more secure.
+
+ Suggest setting Y during development and ironing out driver
+ issues etc. Suggest setting to N if you want faster writing.
+
+ If unsure, say Y.
+
+config YAFFS_EMPTY_LOST_AND_FOUND
+ bool "Empty lost and found on boot"
+ depends on YAFFS_FS
+ default n
+ help
+ If this is enabled then the contents of lost and found is
+ automatically dumped at mount.
+
+ If unsure, say N.
+
+config YAFFS_DISABLE_BLOCK_REFRESHING
+ bool "Disable yaffs2 block refreshing"
+ depends on YAFFS_FS
+ default n
+ help
+ If this is set, then block refreshing is disabled.
+ Block refreshing infrequently refreshes the oldest block in
+ a yaffs2 file system. This mechanism helps to refresh flash to
+ mitigate against data loss. This is particularly useful for MLC.
+
+ If unsure, say N.
+
+config YAFFS_DISABLE_BACKGROUND
+ bool "Disable yaffs2 background processing"
+ depends on YAFFS_FS
+ default n
+ help
+ If this is set, then background processing is disabled.
+ Background processing makes many foreground activities faster.
+
+ If unsure, say N.
+
+config YAFFS_XATTR
+ bool "Enable yaffs2 xattr support"
+ depends on YAFFS_FS
+ default y
+ help
+ If this is set then yaffs2 will provide xattr support.
+ If unsure, say Y.
