[U-Boot] mpc85xx: Put SDHC clock-frequency in device tree
The clock-frequency of SD controller comes from different source on different platform. We add a clock-frequency property in dts file and set the value in u-boot. --- cpu/mpc85xx/fdt.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-)

We do this in fdt_fixup_esdhc()

Ok, I've found this function in the latest tree, so please ignore my patch. Thanks.
