powerpc/T4240EMU: Add T4240EMU target
Add emulator support for T4240. Emulator has limited peripherals and interfaces. Difference between emulator and T4240QDS includes: ECC for DDR is disabled due the procedure to load images No board FPGA (QIXIS) NOR flash has 32-bit port for higher loading speed IFC and I2C timing don't really matter, so set them fast No ethernet Signed-off-by: York Sun <yorksun@freescale.com>
