Bootrom loads SPL from SDCARD or eMMC
according BootPin selection.
Then SPL loads U-Boot on the same mmc device
with the following predefined GPT partitioning:
on SDCARD: gpt partitioning
1: SPL
2: SPL#2
3: U-Boot
4: bootable partition
on eMMC:
The 2 boot partitions are used for SPL (2 copy)
boot1: SPL
boot2: SPL#2
The user partition use gpt partitioning
1: U-Boot
2: bootable partition
This patch select the correct SPL partition
(3 for SDCARD on mmc0 and 1 for eMMC on mmc1)
according the BootRom information saved in TAMP register
and based on configuration flasg:
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION
=> for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new)
=> for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot
And the correct boot_targets is selected according the environment
variables boot_device and boot_instance, with preboot command,
to search the bootable partition with kernel on this device
(generic distro support).
