6ad6c6dc1e sf: stmicro: add support N25Q128 parts
Adds support for Numonyx's N25Q128 SPI flash. These devices
are used on (among others) Avnet Spartan-6 LX9 micro-evaluation
boards. Tested with "sf" commands and CONFIG_ENV_IS_IN_SPI_FLASH.

63ff6a66ae sf: stmicro: support JEDEC standard two-byte signature
There are more than the M25Pxx serial flashs that can be
used with the stmicro driver, for example: the M25PXxx or
N25Qxx serie. All these chips have burned in the original
stmicro manufacture id 0x20 together with a standard
two-byte signature.

In preperation to support all these chips the stmicro driver
have to decode the full two-byte signature.

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.

0dcdbb172c sf: always read 5 bytes for the idcode
Some SPI flash drivers like to have extended id information available
(like the spansion flash), so rather than making it re-issue the ID cmd
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
bytes from all flashes.

9726ba4aba sf: stmicro: drop redundant id read
The common SPI flash code reads the idcode and passes it down to the SPI
flash driver, so there is no need to read it again ourselves.

68f8718df2 spi flash: fix crash due to spi flash miscommunication
Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.
