This series is combination of mtd and sf tunning stuff in previous version patches.[1][2]
This is whole patch series for add mtd support to spi-flash framework and related stuff.
The idea is to introduce the spi-nor flash framework which similar to Linux with driver-model support.
Detail changes:
- drivers/mtd/spi/sf_probe.c: spi-flash to spi drivers interface(dm and non-dm)
- drivers/mtd/spi/sf_ops.c: Core spi-flash functionalities.
- spi_flash ops and dm_spi_ops are not needed as flash opertaion are common for dm and non-dm via MTD
Changes in v7:
- Rebase to master
- Added MTD core support to dataflash
- Few patch bisectable separations
Changes in v6, v5, v4, v3, v2:
- One patch bisectable separation
- Rebase to master
- added newly mtd stuff patches.
Testing: $ git clone git://git.denx.de/u-boot-spi.git $ cd u-boot-spi $ git checkout -b spi-nor-mtd origin/next-spi-nor-mtd

thanks! Jagan.

Thanks.
BTW: Is this series also tested on a board with SPL_DM and DM_SPI and DM_SPI_FLASH enabled? By loading in SPL the main U-Boot image via SPI NOR flash?
I'm asking since I'm currently struggling to get this working on MVEBU. And am experiencing problems with the DM SPI bus and device probing. Without SPL_DM this is working just fine.
Thanks, Stefan
