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
