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.

sf: turn probe switch into a lookup table

2010-10-13T01:08:25+00:00

This allows for arbitrarily long manufacturer ids following the JEDEC
standard of 0x7f continuation bytes.  It also makes adding new entries
easier as it's just one element in an array.  The downside is that it
increases code size a bit, but we're talking ~50 bytes.

sf: spansion: add support for S25FL032P parts

2010-10-07T00:50:38+00:00

This patch introduces an extra mask-field in spansion_spi_flash_params
to support flash chips with 1-byte extended ID (like the S25FL032P).

sf: spansion: fixing erasing when sector size >64KiB

2010-10-07T00:50:38+00:00

The spansion_erase currently only works when the sector size is 64KB.
cmd[1] should contain the higher 8 bit of the 24 bit address of the
sector to be erased. Currently it is holding the sector index to be
erased which happens to be the same thing when the sector size is
64KB.

sf: move useful messages from debug to printf

2010-07-01T03:47:08+00:00

At the moment, the default SPI flash subsystem is quite terse.  Errors and
successes both result in a generic message.  So move the useful errors and
useful successes to printf output by default.

While we're here, also convert the messages to use print_size().

spi_flash: support old STMicro parts with RES

2010-07-01T03:47:08+00:00

Some old STMicro parts do not support JEDEC ID (0x9f). This patch
uses RES (0xab) to get Electronic ID and translates it to JEDEC ID.
