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

jffs2: fix searching for latest version in jffs2_1pass_list_inodes()

2008-12-09T22:38:21Z

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(). Signed-off-by: Alexey Neyman Signed-off-by: Ilya Yanok
