[U-Boot] [PATCH V4 0/9] EXYNOS5: Enable DWMMC, add FDT support for DWMMC and

[Amar]

This patch set enables and initialises DWMMC for Exynos5250 on SMDK5250.
Adds driver changes required for DWMMC.
Adds FDT support for DWMMC.
Adds EMMC boot support for SMDK5250.

This patch set is based on:
"EXYNOS: mmc: support DesignWare Controller for Samsung-SoC", which
is merged in u-boot-mmc.
"Exynos: clock: support get_mmc_clk for exynos".
"Add DT based ethernet driver for SMDK5250".

Changes from V1:
        1)Corrected in response to review comments.
        2)Created separate board files for FDT and non-FDT versions.
        3)Added binding file for DWMMC device node.
        4)Removed the propname 'index' from device node.
        5)Prefixed the vendor name 'samsung' before propname in device node.
        6)Ensured to have same signature for the function exynos_dwmci_init()
        for both FDT and non-FDT versions.
        7)EMMC clock setting has been moved from spl_boot.c to clock_init.c.

Changes from V2:
        1)Updation of commit message and resubmition of proper patch set.

Changes from V3:
        1)Updated to use the macro DWMCI_CTRL_SEND_AS_CCSD instead of the
        hard coded value (1 << 10).
        2)In the file exynos_dw_mmc.c, replaced the new function
        exynos5_mmc_set_clk_div() with the existing function set_mmc_clk().
        set_mmc_clk() will do the purpose.
        3)In the file exynos_dw_mmc.c, computation of FSYS block clock
        divisor (pre-ratio) value is added.
        4)Removed the new function exynos5_mmc_set_clk_div() from clock.c.
