This supports Falcon boot support for Microchip SAMA5D3 Xplained, tested on raw MMC, and on raw NAND. spl_start_uboot() is has the simplest possible implementation. It doesn't test the environment because enabling environment support currently causes the SPL to exceed its maximum size (64 KiB). It doesn't check the serial for incoming characters either because this functionality currently doesn't seem to work from the SPL on this board. Settings for Falcon boot from at FAT partition are also added to avoid compile failures when CONFIG_SPL_OS_BOOT is enabled, but this particular case is currently not functional as adding FAT and partition support cause the SPL to be too big again.
