3ac374c0f0 Add driver for the ST M95xxx SPI EEPROM
This chip is used in a number of boards manufactured by Calao-Systems
which should be supported soon. This driver provides the necessary
spi_read and spi_write functions necessary to communicate with the chip.

2efee52b09 sf: Macronix additional chips supported
new chips supported:-
MX25L1605D, MX25L3205D, MX25L6405D, MX25L12855E
out of which MX25L6405D and MX25L12855E tested on Kirkwood platforms

Modified the Macronix flash support to use 2 bytes of device id instead of 1
This was required to support MX25L12855E

7d907f0ea9 sf: sst: fix sector size
Looks like when I was encoding the sector sizes, I forgot to divide by 8
(due to the stupid marketing driven process that declares all sizes in
useless megabits and not megabytes).

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.

1abe365ffc sf: set common timeouts in seconds, not milliseconds
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
case, but rather increases likely hood of causing problems where none
otherwise exist.

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.

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.
