[PATCH v3 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.

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
