2010-01-15JFFS2: drop support for LZARI compression modeWolfgang Denk
Support for LZARI compression mode was added based on a MTD CVS snapshot of March 13, 2005. However, fs/jffs2/compr_lzari.c contains contradictory licensing terms: the original copyright clause says "All rights reserved. Permission granted for non-commercial use.", but later reference to the file 'LICENCE' in the jffs2 directory was added which says GPL v2 or later. As no boards ever used LZARI compression, and this file is also not present in recent MTD code, we resolve this conflict by removing the conflicting file and references to it. Also copy the referenced but missing file 'LICENCE' from the current MTD source tree. Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-12-21move prototypes for gunzip() and zunzip() to common.hWolfgang Wegner
Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus repeated in every file using it. This patch moves the prototypes to common.h and removes all prototypes distributed anywhere else. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>
2009-12-08common: delete CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOULHeiko Schocher
There is more and more usage of printing 64bit values, so enable this feature generally, and delete the CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL defines. Signed-off-by: Heiko Schocher <hs@denx.de>
2009-12-05EXT2FS: fix inode size for ext2fs rev#0Michael Brandt
extfs.c assumes that there is always a valid inode_size field in the superblock. But this is not true for ext2fs rev 0. Such ext2fs images are for instance generated by genext2fs. Symptoms on ARM machines are messages like: "raise: Signal # 8 caught"; on PowerPC "ext2ls" will print nothing. This fix checks for rev 0 and uses then 128 bytes as inode size.

2009-10-03Conditionally perform common relocation fixupsPeter Tyser
Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-09-28ubifs: Correct dereferencing of files-after-symlinksSimon Kagstrom
Files in directories which are symlinked to were not dereferenced correctly in last commit. E.g., with a symlink /boot/lnk -> /boot/real_dir loading /boot/lnk/uImage will fail. This patch fixes that by simply seeing to it that the target base directory has a slash after it.

2009-09-23ubifs: Add support for looking up directory and relative symlinksSimon Kagstrom
This patch adds support for resolving symlinks to directories as well as relative symlinks. Symlinks are now always resolved during file lookup, so the load stage no longer needs to special-case them.

2009-09-15Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom
__set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
2009-08-21jffs2: some fixes to summary supportIlya Yanok
This patch fixes some issues with JFFS2 summary support in U-Boot. 1/ Summary support made compilation configurable (as summary support considered expiremental even in Linux). 2/ Summary code can do unaligned 16-bit and 32-bit memory accesses. We need to get data byte by byte to exclude data aborts. 3/ Make summary scan in two passes so we can safely fall back to full scan if we found unsupported entry in the summary.

2009-08-18jffs2: clean the cache in case of malloc fails in build_listsIlya Yanok
We should call jffs2_clean_cache() if we return from jffs2_build_lists() with an error to prevent usage of incomplete lists. Also we should free() a local buffer to prevent memory leaks. Signed-off-by: Ilya Yanok <yanok@emcraft.com>

2009-07-16Remove legacy NAND and disk on chip code.Scott Wood
Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

2009-06-12FAT replace compare_sign with strncmp.Tom Rix
The static function compare_sign is only used to compare the fs_type string and does not do anything more than what strncmp does. The addition of the trailing '\0' to fs_type, while legal, is not needed because the it is never printed out and strncmp does not depend on NULL terminated strings.

2009-04-28UBIFS: fix recovery bugAdrian Hunter
UBIFS did not recovery in a situation in which it could have. The relevant function assumed there could not be more nodes in an eraseblock after a corrupted node, but in fact the last (NAND) page written might contain anything. The correct approach is to check for empty space (0xFF bytes) from then on. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Stefan Roese <sr@denx.de>

2009-04-04UBIFS: add R/O compatibilityArtem Bityutskiy
Now UBIFS is supported by u-boot. If we ever decide to change the media format, then people will have to upgrade their u-boots to mount new format images. However, very often it is possible to preserve R/O forward-compatibility, even though the write forward-compatibility is not preserved. This patch introduces a new super-block field which stores the R/O compatibility version.

2009-04-03mflash: Initial mflash supportunsik Kim
Mflash is fusion memory device mainly targeted consumer eletronic and mobile phone. Internally, it have nand flash and other hardware logics and supports some different operation (ATA, IO, XIP) modes. IO mode is custom mode for the host that doesn't have IDE interface. (Many mobile targeted SoC doesn't have IDE bus) This driver support mflash IO mode. Followings are brief descriptions about IO mode. 1. IO mode based on ATA protocol and uses some custom command. (read confirm, write confirm) 2. IO mode uses SRAM bus interface. Signed-off-by: unsik Kim <donari75@gmail.com>
2009-03-20UBIFS: Missing offset relocation for compressor 'none'Michael Lawnick
On systems where U-Boot is linked to another address than it really lays (e.g. backup image), calls via function pointers must be fixed with a '+= gd->reloc_off'. This was not done for none_compr in ubifs_compressors_init() what leads to system crash on ubifsmount command. Signed-off-by: Michael Lawnick <ml.lawnick@gmx.de> Acked-by: Stefan Roese <sr@denx.de>
2009-03-20UBIFS: Implement read-only UBIFS support in U-BootStefan Roese
The U-Boot UBIFS implementation is largely a direct copy from the current Linux version (2.6.29-rc6). As already done in the UBI version we have an "abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock() ...). This makes it possible to use the original Linux code with very little changes. And by this we can better update to later Linux versions. I removed some of the Linux features that are not used in the U-Boot version (e.g. garbage-collection, write support).

2009-01-24fat: fix unaligned errorsBryan Wu
A couple of buffers in the fat code are declared as an array of bytes. But it is then cast up to a structure with 16bit and 32bit members.

2008-12-09jffs2: cache data_crc resultsIlya Yanok
As we moved data_crc() invocation from jffs2_1pass_build_lists() to jffs2_1pass_read_inode() data_crc is going to be calculated on each inode access. This patch adds caching of data_crc() results. There is no significant improvement in speed (because of flash access caching added in previous patch I think, crc in RAM is really fast) but this patch impacts memory usage -- every b_node structure uses 12 bytes instead of 8.

2008-12-09jffs2: add buffer to cache flash accessesIlya Yanok

2008-12-04Remove non-ascii characters from fat codeRemy Bohmer
This code contains some non-ascii characters in comment lines and code. Most editors do not display those characters properly and editing those files results always in diffs at these places which are usually not required to be changed at all. This is error prone. So, remove those weird characters and replace them by normal C-style equivalents for which the proper defines were already in the header. Signed-off-by: Remy Bohmer <linux@bohmer.net>

2008-08-21Make the YAFFS filesystem workRemy Bohmer
Recently the YAFFS filesystem support has been added to U-boot. However, just enabling CONFIG_YAFFS2 is not enough to get it working. ymount will generate an exception (when dereferencing mtd->readoob()), because the genericDevice is a null pointer. Further, a lot of logging is produced while using YAFFS fs, so logging should also be disabled. Both issues are solved by this patch. With this patch and CONFIG_YAFFS2 enabled, I get a readable filesystem in U-boot, as well as in Linux. Tested on a Atmel AT91SAM9261EK board.
