Ported from the asahi-quattro lane. Both are pinned by hand like linux-aurora and restricted to aarch64 and the edge channel from their first merge, since merging publishes. pkgrel sits one above the fork lanes' builds so the same filename never carries two sets of bytes.

Subject: [PATCH v4] disk: dos: Add all options for EFI System Partitions
|
|
|
|
The EFI spec states that the ESP can be any of FAT12/16/32 but for
|
|
compatibility doesn't necssarily require the partition to be the
|
|
EFI partition table ID of 0xef. A number of arm devices will not
|
|
find their firmware on a FAT partition with an ID of 0xef so also
|
|
allow the original FAT12/16/32 partition IDs as they are also
|
|
permissable for an ESP.
