Support for both external (NOR) and internal (SD Card) boot mode are added. It uses the generic SPL framework to implement the internal boot mode. The following peripherals are supported: - Ethernet (FEC) - SD Card - NAND (512 MB) - NOR Flash In the internal boot mode, a simple imximage header is generated to set the address in internal RAM where the SOC must copy the SPL code. The initial setup is then demanded to the SPL itself.

The mmu_set_region_dcache_behaviour() function allows drivers to make these changes after the MMU is set up. It is implemented only for ARMv7 at present. This is needed for LCD support, where we want to make the LCD frame buffer write-through (or off) rather than write-back.

Right now, there are two almost identical functions to setup VDDIO and VDDD, which is prone to breakage. Pull out the differences into constant structure and pass them as an argument to the common function. Moreover, the function has almost identical loops for setting higher and lower VDDx voltage. Merge these two loops.
