With this patch, it is possible to get the offset and size information
from the mtdpartiton setting in "mtdparts", similiar to the
"nand" commandos.=> sf
sf - SPI flash sub-systemUsage:
sf probe [[bus:]cs] [hz] [mode] - init flash device on given SPI bus
and chip select
sf read addr offset|partition len - read `len' bytes starting at
`offset' to memory at `addr'
sf write addr offset|partition len - write `len' bytes from memory
at `addr' to flash at `offset'
sf erase offset|partition [+]len - erase `len' bytes from `offset'
`+len' round up `len' to block size
sf update addr offset|partition len - erase and write `len' bytes from memory
at `addr' to flash at `offset'
=>
for example "env" is defined in mtdparts:=> sf read 13000000 env

MTD, UBI/UBIFS sync.Note (From Jagan): For testing raw mtd parition erase/read/write operations
using cmd_sf, sf_mtd should be required to register the spi flash device to
MTD layer but the sf_mtd_info ops were not required until and unless if we
use any flash filesystem layer say for example UBI. Due to this the foot-print
got increased ~290bytes in non-UBI case here that should be acceptible.Signed-off-by: Daniel Schwierzeck

in the range of 0x7Fxxxxxx, which generates a data abort when the
kernel tries to read it. Config the u-boot environment to load

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.Remove the configs that behave this way from the archs.
A few configs still remain, but that is because they only exist as
defaults and do not have a proper Kconfig entry. Those appear to be:SPIFLASH
