Enable A/B
As boot_control HAL is now implemented for AM57x, we can enable A/B
updates. Slotted partitions are specified in AB_OTA_PARTITIONS.
Related changes should be implemented in bootloader (partition table).
See [0] for implementation details.
Next changes are made w.r.t. boot flow:
- system is mounted as root, so "skip_initramfs" must be added to
kernel cmdline when normal boot is requested
- recovery image is not built, so recovery partition can be deleted
(in partition table and in fstab)
- ramdisk in boot.img contains recovery functionality and should be
booted when recovery boot is requested (without "skip_initramfs"
parameter in kernel cmdline)
- for partitions specified in AB_OTA_PARTITIONS there should be two
versions in partition table: with "_a" and "_b" suffixes
