[PATCH v1 0/2] SPL EBBR - EFI System Partition support

[Mayuresh Chitale <mchitale@ventanamicro.com>]

This series adds support to locate an EFI System Partition on a disk and
boot the next stage from such a parition if found. The next stage image
is expected to be under the FIRMWARE directory as described in the EBBR
specification [1]. Also update the spl_blk_fs and spl_fat drivers to
prefer booting from ESP and fall back to the configured parition in
case of a failure.

These patches are built on top of the following series from Sean Anderson:
