ARMV7: Add support for TI OMAP4 Panda
OMAP4 Panda is a reference board based on OMAP4430, an ARMV7 Cortex A9 CPU This patch adds basic support for booting the board. It includes i2c and mmc support. It assumes U-boot is loaded to SDRAM with the help of another small bootloader (x-load) running from SRAM. U-boot currently relies on x-load for clock, mux, and SDRAM initialization Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
