c4e932ce73 sf: unify erase commands
Analysis of the flash drivers shows that they all use 0x20 if the erase
size is 4KiB, or 0xd8 if it's larger.  So with this info in hand, we can
unify all the erase functionality in one place.

a4ed3b6531 sf: inline data constants
I imagine much of these constants are due to copy & pasting previous
drivers rather than an actual reflection of the hardware layout.  At
any rate, inline the info that we don't care about externally as it
shrinks things nicely.

No need for dedicated defines when these really only get used once.

b4c87d658c sf: drop unused/duplicate command defines
In an effort to unify the spi flash drivers further, drop all the
unused and/or duplicate command defines.

b06afa75fa sf: kill off now-unused local state
Now that the common spi_flash structure tracks all the info that these
drivers need, kill off their local state indirection and use just what
the common code provides.

d4aa500913 sf: unify write funcs
Once we add a new page_size field for write lengths, we can unify the
write methods for most of the spi flash drivers.

Every spi flash uses the same write enable command, so unify this in
the common code.

f8f0757dcb sf: localize erase funcs
No need for these to be exported as they are only accessed indirectly
via function pointers.

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).

6163045bcd sf: unify status polling for ready bit
All of the spi flash drivers implement the status register polling for
detecting the device ready state, so unify them all in a new helper
function -- spi_flash_wait_ready.

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.
