Implement support for saving ARM register R4 early during boot using save_boot_params . Implement support for decoding the stored register R4 value in spl_boot_device() to obtain boot device from which the SoC booted. This way, the SPL will always load U-Boot from the same device from which the SPL itself booted instead of using hard-coded boot device. This functionality is useful for example when booting sama5d2-xplained from SD card, where by default the SPL would try loading the U-Boot from eMMC and fail. This is because eMMC is on SDHCI0 (BOOT_DEVICE_MMC1), while SD slot is on SDHCI1 (BOOT_DEVICE_MMC2) and the SPL was hard-wired to always boot from BOOT_DEVICE_MMC1.
