resync mtd, ubi and ubifs subsystem with linux:
commit 455c6fdbd219161bd09b1165f11699d6d73de11c
Author: Linus Torvalds torva...@linux-foundation.org
Date: Sun Mar 30 20:40:15 2014 -0700
Linux 3.14
Main reason for this sync is, we now have UBI fastmap support
in U-Boot.
Tested it on am33xx, imx6 and mpc83xx boards. MAKEALL for arm and powerpc
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 patchserie!
The patches
lib, rbtree: resync with Linux-3.14
lib, list_sort: add list_sort from linux 3.14
mtd, ubi, ubifs: resync with Linux-3.14
are not checkpatch clean, as they use code from Linux and
I do not want to change this.
Remarks:
- UBI Fastmap is now availiable in U-Boot
activate it with CONFIG_MTD_UBI_FASTMAP
- 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.
- move a lot of defines from include/ubi_uboot.h to
include/linux/compat.h, as this is the correcter place for it.
- add usb device to linux device, so usb uses struct device
from linux/compat.h
- 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 8000 8 ${filesize}
would not work with it ...
- add CONFIG_MTD_NAND_VERIFY_WRITE from U-Boot code
(only compile tested)
- Documented the config defines in README
- kmalloc now uses memalign for allocating memory. This prevented
crashes when tested ubi/ubifs on imx6 board.
- To produce this patch I did three steps:
- copied the linux source files to U-Boot tree - commit this
- adapt license text in each file - commit this
- make the code again compile clean and working - commit this
Then squashed this three patches to this patch, to not break
bisectability. To make further sync with linux easier, the
above three 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
This branch is only thought for further linux syncs! Please
do not use this branch for testing this patchseries!
- Hope I get all U-Boot specific changes ... so please, test,
test, test ...
- changes for v2:
- add lib/linux_compat.c as Joerg Krause detected
