46f46fd48e jffs2:jffs2_1pass.c: remove double braces
Clang interpretes an if condition like  "if ((a = b) == NULL)
as it tries to assign a value in a statement. Hence if you do
"if ((something)) it warns you that you might be confused.
Hence drop the double braces for plane if statements.

f098337152 JFFS2: drop support for LZARI compression mode
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.

8cf19b9fec jffs2: some fixes to summary support
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.

b644006e1a jffs2: clean the cache in case of malloc fails in build_lists
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.

be33b046b5 Remove legacy NAND and disk on chip code.
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.

Include <linux/mtd/compat.h> header for min_t definition instead of
providing our own one. Removes warnings in case of OneNAND support

142a80ffc3 jffs2: cache data_crc results
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.
