From: Rex Chang rchang@ti.com
Added support for K2G EVM with FlipChip SoC of which ARM/DDR3 runs at 1GHz/1066 MT/s. The patch is also backward compatible with old revision EVM and EVM with WireBond SoC. Their ARM/DDR3 run at 600MHz/800 MT/s.
The new SoC supports 2 different speeds at 1GHz and 600MHz. Modyfied the CPU Name to show which SoC is used in the EVM. Modified the DDR3 configuration to reflect New SoC supports 2 different CPU and DDR3 speeds, 1GHz/1066MT and 600MHz/800MT.
Added new inline function board_it_k2g_g1() for the new FlipChip 1GHz, and set the u-boot env variable board_name accordingly.
Modified findfdt script in u-boot environment variable to include new k2g board type.
