From: Randolph Sapp <[email protected]> Add support for EFI capsules for this device. One large caveat is that the partition holding boot binaries cannot be the ESP partition due to the following ROM limitations.
- The boot disk must be MBR - The boot partition must be labeled 0x0c with a boot flag A separate ESP partition should be provided for EFI capabilities.
