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.
Changes in v3: - Revert fallback change from v2 - Fix part_get_esp signature and header in part.h - Add RB tag
Changes in v2: - Rebase on latest next branch - Enable SPL_ESP_BOOT by default - For NVMe boot, remove fallback in case of ESP boot failure
Mayuresh Chitale (2): part: Add a function to find ESP partition spl: Add support for booting from ESP
