8875bdb341 sf: sst: support newer standardized flashes
Newer SST flashes have dropped the Auto Address Increment (AAI) word
programming (WP) modes in favor of the standard page programming mode
that most flashes now support.  So add a flags field to the different
flashes to support both modes with new and old styles.

4e6a515899 sf: add struct spi_flash.sector_size parameter
This patch adds a new member to struct spi_flash (u16 sector_size)
and updates the spi flash drivers to start populating it.

This parameter can be used by spi flash commands that need to round
up units of operation to the flash's sector_size.

Having this number in one place also allows duplicated code to be
further collapsed into one common location (such as erase parameter
and the detected message).

6d8962e814 Switch from archive libraries to partial linking
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.

0d3fe2b153 sf: turn probe switch into a lookup table
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.

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

64KB.

b376bbb49f sf: move useful messages from debug to printf

d9596ffbdc sf: stmicro: dont send 4 bytes when reading status register
I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result.  Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately.  So only write out the
read status register opcode before polling the result.

Since timeouts are only hit when there is a problem in the system, we
don't want to prematurely timeout on a functioning setup.  Thus having
low timeouts (in milliseconds) doesn't gain us anything in the production

otherwise exist.

to get at the last 2 bytes, have the common code read 5 bytes rather than
just 3.  This also matches the Linux behavior where it always reads 5 id
