mtd, ubi, ubifs: resync with Linux-3.14

resync ubi subsystem with linux:

commit 455c6fdbd219161bd09b1165f11699d6d73de11c

Author: Linus Torvalds <[email protected]>

    Linux 3.14

A nice side effect of this, is we introduce UBI Fastmap support to U-Boot.

To produce this patch I did two steps:
- simple copy following files from linux to u-boot

drivers/mtd/mtdconcat.c drivers/mtd/mtdcore.c drivers/mtd/mtdpart.c drivers/mtd/ubi/attach.c drivers/mtd/ubi/build.c drivers/mtd/ubi/debug.c drivers/mtd/ubi/debug.h drivers/mtd/ubi/eba.c drivers/mtd/ubi/fastmap.c drivers/mtd/ubi/io.c drivers/mtd/ubi/kapi.c drivers/mtd/ubi/misc.c drivers/mtd/ubi/ubi-media.h drivers/mtd/ubi/ubi.h drivers/mtd/ubi/upd.c drivers/mtd/ubi/vmt.c drivers/mtd/ubi/vtbl.c drivers/mtd/ubi/wl.c fs/ubifs/budget.c
fs/ubifs/debug.c
fs/ubifs/debug.h
fs/ubifs/io.c
fs/ubifs/key.h
fs/ubifs/log.c
fs/ubifs/lprops.c
fs/ubifs/lpt.c fs/ubifs/lpt_commit.c fs/ubifs/master.c
fs/ubifs/misc.h
fs/ubifs/orphan.c fs/ubifs/recovery.c fs/ubifs/replay.c
fs/ubifs/sb.c
fs/ubifs/scan.c
fs/ubifs/super.c
fs/ubifs/tnc.c
fs/ubifs/tnc_misc.c fs/ubifs/ubifs-media.h fs/ubifs/ubifs.h include/linux/mtd/bbm.h include/linux/mtd/flashchip.h include/linux/mtd/mtd.h include/linux/mtd/nand.h include/linux/mtd/partitions.h include/linux/mtd/ubi.h

include/uapi/mtd/mtd-abi.h -> include/linux/mtd include/uapi/mtd/ubi-user.h -> include/linux/mtd

- make the code again compile clean and working -> commit this adapt the Linux code to compile and work with U-Boot.

Then squash this two patches to this patch, to not break bisectability. To make further sync with linux easier, the above two patches can be found in:

http://git.denx.de/?p=u-boot/u-boot-testing.git;a=shortlog;h=refs/heads/update-mtd%2Bubi-linux-v3.14

Please do not use this branch for testing this patchserie!

summary of changes for U-Boot adaptions:
- replace UBI_LINUX in current UBI code from U-Boot with __UBOOT__ as this define is used in other places in U-Boot where code from other projects is used.

- UBI Fastmap is now availiable in U-Boot activate it with CONFIG_MTD_UBI_FASTMAP

- onenand changes only compile tested.

- Following Code in drivers/mtd/nand/nand_base.c nand_do_write_ops() adapted for U-Boot:

      +#ifndef __UBOOT__
            /* Reject writes, which are not page aligned */
            if (NOTALIGNED(to) || NOTALIGNED(ops->len)) {
      +else
      +     /* Reject writes, which are not page aligned */
      +     if (NOTALIGNED(to)) {
      +endif

as the original linux code leads in not working use of the env var "filesize". For example a "nand write 80000000 80000 ${filesize}" would not work with it ...

- add CONFIG_MTD_NAND_VERIFY_WRITE from U-Boot code

- Documented the config defines in README

- kmalloc now uses memalign for allocating memory

Tested it on am33xx, imx6 and mpc83xx boards. MAKEALL for arm and powerpc and mips compiles clean.

Tested UBI fastmap on a board with 512 MiB nand flash. Attach time from old U-Boot was 2 seconds, reduced with UBI fastmap to 0.2 seconds.

Please test this patch!

- changes for v2:
- add lib/linux_compat.c as Joerg Krause detected
- changes for v3:
rebase with current U-Boot commit 61e76f53708cf082ef9061a140b57df3513b8ba1
- changes for v4:
- rebase with commit d8a97f934c64a7ba6f11da5e4cc7f3be57fcb82d
- remove compile error for mips, as Tom Rini suggested check "MAKEALL mips" compiles clean
- fix blackfin and microblaze compile
add fix for blackfin from Trom Rini also add his Signed-off-by

- changes for v5:
- extract linux/compat.h changes

Heiko Schocher (5):
lib, rbtree: resync with Linux-3.14
lib, list_sort: add list_sort from linux 3.14 linux include: add ERR_CAST
lib, linux: move linux specific defines to linux/compat.h mtd, ubi, ubifs: resync with Linux-3.14
