fs/jffs2/mini_inflate.c: use "static inline" instead of "inline"

2017-10-16T13:42:51Z

This makes gcc no longer expect an out-of-line version of the functions being present elsewhere. This fixes a failure to build on several marvell targets with gcc-7 on Debian: https://bugs.debian.org/877963 Signed-off-by: Adrian Bunk Signed-off-by: Vagrant Cascadian

jffs2: ECC corrected nand data is ignored

2017-10-16T13:42:51Z

Hello, I ran into a problem with the JFFS2 filesystem driver implemented in U-Boot. I've got a NAND device that has correctable ECC errors (corrected somewhere in mtd/nand/nand_base.c). The NAND driver tells the filesystem layer (jffs2_1pass.c) above that there occurred correctable ECC errors and returns with a "value > 0". The JFFS2 driver recognizes the corrected ECC errors as real error and skips this block because the only accepts a "return value == 0" as correct. This problem exists for over 8 years (I checked version 2010.09) so I'm a little bit worried that I interpreted something wrong or didn't get the whole context. Can someone confirm this bug (and the bugfix) in the u-boot jffs2 driver? There was a mail in 2012 that mentioned the same problem, but there was no patch: http://u-boot.10912.n7.nabble.com/JFFS2-seems-to-drop-nand-data-with-ECC-corrections-td142008.html Sometime after this discussion the return value of nand_read() changed from -EUCLEAN as correctable ECC error to a positive value with the count of ECC corrected errors. With kind reguards, Uwe Engling

treewide: replace with error() with pr_err()

2017-10-04T15:59:44Z

U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // @@@@ -error +pr_err (...) // Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass [trini: Re-run Coccinelle] Signed-off-by: Tom Rini

fs: use get_nand_dev_by_index()

As part of preparation for nand DM conversion the new API has been introduced to remove direct access to nand_info array. So, use it here instead of accessing to nand_info array directly. Signed-off-by: Grygorii Strashko

fs: Kconfig: Add a separate option for FS_JFFS2

2017-05-22T16:45:31Z

Rather than using CMD_JFFS2 for both the filesystem and its command, we should have a separate option for each. This allows us to enable JFFS2 support without the command, if desired, which reduces U-Boot's size slightly. Signed-off-by: Simon Glass

nand: Embed mtd_info in struct nand_chip

2016-06-04T01:27:48Z

nand_info[] is now an array of pointers, with the actual mtd_info instance embedded in struct nand_chip. This is in preparation for syncing the NAND code with Linux 4.6, which makes the same change to struct nand_chip. It's in a separate commit due to the large amount of changes required to accommodate the change to nand_info[]. Signed-off-by: Scott Wood

JFFS2: Use merge sort when parsing filesystem

2015-08-13T00:47:32Z

When building the file system the existing code does an insertion into a linked list. It attempts to speed this up by keeping a pointer to where the last entry was inserted but it's still slow. Now the nodes are just inserted into the list without searching through for the correct place. This unsorted list is then sorted once using mergesort after all the entries have been added to the list. This speeds up the scanning of the flash file system considerably.
