This patchserie add the popssibility to define mtd partitions on
spi nor flash, and use this settings with the sf commands.
steps:
- add MTD layer driver for spi, original patch from:
http://git.denx.de/?p=u-boot/u-boot-mips.git;a=commitdiff;h=bb246819cdc90493dd7089eaa51b9e639765cced
and addapted it to current mainline.
- move common functions to get offset and size from
cmdline nand command to extract offset and size from
a mtd partition to common place "drivers/mtd/mtd_uboot.c"
maybe another place is better?
- add to the sf command the possibility to use offset and size from
the settings in mtdparts
With this patchset, the sf command looks now:
=> sf
sf - SPI flash sub-system
Usage:
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
device 0 offset 0xd0000, size 0x10000
SF: 65536 bytes @ 0xd0000 Read: OK
=>
There are the followings checkpatch warnings:

has style problems, please review.
I see not, why this warning pops up ...
- changes for v2:
- mtd-spi-add-MTD-layer-driver.patch
- add comment from Daniel Schwierzeck:
fix compile error from original patch with
"static inline" rather than "static __maybe_unused"
- changes for v3:
- rebase with d6c1ffc7d23f4fe4ae8c91101861055b8e1501b6
- add comments from scott wood:
- align MTD_DEV_TYPE_NAND correct
- remove unnecessary inline
- rework "jffs2 header" problem later

ping? Do you have any objections against this patchseries, or do you
think it is ok?
