Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

JFFS2: drop support for LZARI compression mode

2010-01-15T10:16:47+00:00

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.

jffs2: some fixes to summary support

2009-08-21T21:29:35+00:00

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

2009-08-18T19:30:58+00:00

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.

Remove legacy NAND and disk on chip code.

2009-07-17T00:07:47+00:00

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

2008-12-16T16:14:54+00:00

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...

jffs2: cache data_crc results

2008-12-09T22:40:01+00:00

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.
