[U-Boot] [PATCH v4 0/2] SMDKV310 Board Support

[U-Boot] [PATCH v4 0/2] SMDKV310 Board Support

[Chander Kashyap]

Hi,
This patchset adds support for a new board SMDKV310, based on S5PV310 SOC.
This SOC is very similar to S5PC210 SOC, hence we are re-using this SOC code.

Specific changes in PATCH v3 are mentioned in specific patch files.

Chander Kashyap (2):
  ARMV7: Add support for Samsung SMDKV310 Board
  ARMV7: MMC SPL Boot support for SMDKV310 board

[U-Boot] [PATCH v4 1/2] ARMV7: Add support for Samsung SMDKV310 Board

[Chander Kashyap]

SMDKV310 board is based on Samsung S5PV310 SOC. This SOC is very much
similar to S5PC210.

[U-Boot] [PATCH v4 2/2] ARMV7: MMC SPL Boot support for SMDKV310 board

[Chander Kashyap]

Added MMC SPL boot support for SMDKV310. This framework design is
based on nand_spl support.

Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org>
---
Changes for v3:
	- spl file renamed to u-boot-mmc-spl.bin
	- spl directory renamed to mmc_spl
	- comments added in mkv310_image.c file
