JFFS2: drop support for LZARI compression mode

2010-01-15T10:16:47Z

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

jffs2: some fixes to summary support

2009-08-21T21:29:35Z

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.

jffs2: clean the cache in case of malloc fails in build_lists

2009-08-18T19:30:58Z

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

Remove legacy NAND and disk on chip code.

2009-07-17T00:07:47Z

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.

jffs2: include instead of defining own min_t

2008-12-16T16:14:54Z

Include header for min_t definition instead of providing our own one. Removes warnings in case of OneNAND support enabled. Although I thinks it's a bit silly to include just for min_t... Signed-off-by: Ilya Yanok Acked-by: Stefan Roese

jffs2: cache data_crc results

2008-12-09T22:40:01Z

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.

jffs2: summary support

2008-12-09T22:39:59Z

This patch adds support for reading fs information from summary node instead of scanning full eraseblock. Signed-off-by: Ilya Yanok

jffs2: add buffer to cache flash accesses

2008-12-09T22:39:58Z

With this patch JFFS2 code allocates memory buffer of max_totlen size (size of the largest node, calculated during scan time) and uses it to store entire node. Speeds up loading. If malloc fails we use old ways to do things. Signed-off-by: Alexey Neyman Signed-off-by: Ilya Yanok

jffs2: rewrite jffs2 scanning code based on Linux one

2008-12-09T22:39:16Z

Rewrites jffs2_1pass_build_lists() function in style of Linux's jffs2_scan_medium() and jffs2_scan_eraseblock(). This includes: - Caching flash acceses - Smart dealing with free space Signed-off-by: Alexey Neyman Signed-off-by: Ilya Yanok
