ff0dc2c433 sf: spansion: add support for S25FL032P parts
This patch introduces an extra mask-field in spansion_spi_flash_params
to support flash chips with 1-byte extended ID (like the S25FL032P).

c3cb09207f sf: spansion: fixing erasing when sector size >64KiB
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.

b376bbb49f sf: move useful messages from debug to printf
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().

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.
