* jffs2: some fixes to summary supportIlya Yanok2009-08-21-41/+81
| | | | | | | | | | | | 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_listsIlya Yanok2009-08-18-3/+14
| | | | | | | | 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>
* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-20/+0
| | | | | | | | | | | | | 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 <linux/mtd/compat.h> instead of defining own min_tIlya Yanok2008-12-16-5/+1
| | | | | | | | | | | | Include <linux/mtd/compat.h> 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 <linux/mtd/compat.h> just for min_t... Signed-off-by: Ilya Yanok <yanok@emcraft.com> Acked-by: Stefan Roese <sr@denx.de>
* jffs2: cache data_crc resultsIlya Yanok2008-12-09-1/+4
| | | | | | | | | | | | | 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 supportIlya Yanok2008-12-09-1/+186
| | | | | | | This patch adds support for reading fs information from summary node instead of scanning full eraseblock. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* jffs2: add buffer to cache flash accessesIlya Yanok2008-12-09-44/+72
| | | | | | | | | | 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 <avn@emcraft.com> Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* jffs2: rewrite jffs2 scanning code based on Linux oneIlya Yanok2008-12-09-56/+171
| | | | | | | | | | | 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 <avn@emcraft.com> Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* jffs2: fix searching for latest version in jffs2_1pass_list_inodes()Ilya Yanok2008-12-09-3/+2
| | | | | | | | | We need to update i_version inside cycle to find really latest version inside jffs2_1pass_list_inodes(). With that fixed we can use isize inside dump_inode() instead of calling expensive jffs2_1pass_read_inode().
