[U-Boot] [Patch V2 0/4] Migrate DA850-evm to Driver Model

[U-Boot] [Patch V2 0/4] Migrate DA850-evm to Driver Model

[Adam Ford]

This series adds the DA850-evm device tree and related dependant files, along
with enabling DM_SPI, DM_SERIAL, and DM_SPI with DM_SPIFLASH.

This is a resend of the original series. The only real change to this series 
from V1 is the additional adding of MTD PARTS and I2C.  

Adam Ford (4):
  spi: davinci_spi: Add da830-spi support for DM
  arm: da850-evm: Enable DM and device tree support for da850-evm
  arm: da850-evm: Enable MTD Parts
  ARM: da850-evm: Enable DM_I2C

[U-Boot] [Patch V2 1/4] spi: davinci_spi: Add da830-spi support for DM

[Adam Ford]

The DM support is already in the driver, so add
da830-spi to the compatible list.

[U-Boot] [Patch V2 3/4] arm: da850-evm: Enable MTD Parts

[Adam Ford]

There is a discrepency between U-Boot and Linux on the partition map.
This enabes the MTD parts to pass MTD partition information from U-Boot to
Linux.  Linux already has a pending patch to enable MTD PARTS in
davinci_all_defconfig
