* ARM: sama5d2: Implement boot device autodetectionMarek Vasut2016-05-24-1/+67
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Starting with 96e5b03 we use a linker list for partition table information. However since we use this in SPL we need to make sure that the SPL linker scripts include these as well. While doing this, it's best to simply include all linker lists to future proof ourselves.
