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=bb246819cdc90493...
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 =>

I see not, why this warning pops up ...
resend rebased version of this series, as v3 is pending since September 2014...
Changes in v6:
- add comments from Jagan Teki: new patch in this patchserie, extract this piece of code into a new patch.
Changes in v2:
- add comment from Daniel Schwierzeck: fix compile error from original patch with "static inline" rather than "static __maybe_unused"
Changes in v3:
- rebase with d6c1ffc7d23f4fe4ae8c91101861055b8e1501b6
- add comments from scott wood:
- align MTD_DEV_TYPE_NAND correct
- remove unnecessary inline
- rework "jffs2 header" problem later
Changes in v4:
- rebased against 385a08a60f042061b004642d6b9bb6cfb794ad5a
Changes in v5:
- add comment from Scott Wood: keep the continuation line aligned with the arguments
Changes in v6:
- add comments from Jagan Teki: move code, which checks if flash pointer is used into a new patch.
- use #ifdef in Code
- call mtd register before the spi_release_bus
- add Reviewed-by: Jagannadha Sutradharudu Teki jagannadh.teki@gmail.com
- fix Tom Rinis mail addr
- add comment from Scott Wood:
- fix indentation level
- add mtd_ prefix
- move str2off and str2long into common place, as they are no mtd specific functions and change return value from int to bool
- add comment from Jagan Teki:
- append help text
- add Reviewed-by from Jagannadha Sutradharudu Teki
Daniel Schwierzeck (1): mtd, spi: add MTD layer driver
Heiko Schocher (3): mtd, nand: move common functions from cmd_nand.c to common place spi, sf: use offset and size in sf cmd from mtdpartition mtd, spi: check if flash pointer is used

I got no more comment for this v6. Are there any more issues? If not I vote for apllying it soon, so we have some tests before the next release... thanks!
Let me give some more time I will test and see any final comments.
I will pick this series, once all fine.
Ok, thanks!
bye, Heiko
