Re: [PATCH 2/3] stm32mp: stm32prog: Add support of ESP partition type

On 6/8/23 17:09, Patrick Delaunay wrote:

Add support of "ESP" partition type in flashlayout to select the "EFI System Partition", associated to U-Boot "system" partition type guid, PARTITION_SYSTEM_GUID = C12A7328-F81F-11d2-BA4B-00A0C93EC93B.

This partition is the bootable partition for efi boot.
