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: https://lists.denx.de/pipermail/u-boot/2023-August/525665.html
