spi, sf: Use offset and size in sf cmd from mtdpartition

2015-06-29T19:10:11+00:00

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-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

zynq-uboot> mtdparts add nor0 0x10000@0x0 env
zynq-uboot> sf erase env 0x10000
SF: 65536 bytes @ 0x0 Erased: OK

zynq-uboot> sf write 0x100 env
device 0 offset 0x0, size 0x10000
SF: 65536 bytes @ 0x0 Written: OK

zynq-uboot> sf read 0x40000 env
device 0 offset 0x0, size 0x10000
SF: 65536 bytes @ 0x0 Read: OK

mtd, nand: Move common functions from cmd_nand.c to common place

2015-06-29T19:10:11+00:00

Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.

For onenand the arg_off_size() is left in common/cmd_onenand.c.
It should use now the common arg_off() function, but as I could
not test onenand I let it there ...

mtd, spi: Add MTD layer driver

2015-06-29T19:10:11+00:00

Add MTD layer driver for spi, original patch from:
http://git.denx.de/?p=u-boot/u-boot-mips.git;a=commitdiff;h=bb246819cdc90493dd7089eaa51b9e639765cced

Changes from Heiko Schocher against this patch:
- Remove compile error if not defining CONFIG_SPI_FLASH_MTD:

  LD      drivers/mtd/spi/built-in.o
drivers/mtd/spi/sf_probe.o: In function `spi_flash_mtd_unregister':
/home/hs/abb/imx6/u-boot/drivers/mtd/spi/sf_internal.h:168: multiple definition of `spi_flash_mtd_unregister'

make[1]: *** [drivers/mtd/spi/built-in.o] Fehler 1
make: *** [drivers/mtd/spi] Fehler 2

- Add a README entry.
- Add correct writebufsize, to fit with Linux v3.14
  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.
