[PATCH v3 0/3] spl: allow loading via partition type GUID

[Heinrich Schuchardt]

Some boards provide main U-Boot as a dedicated partition to SPL.
Currently we can define either a fixed partition number or an MBR
partition type to define which partition is to be used.

Partition numbers tend to conflict with established partitioning schemes
of Linux distros. MBR partitioning is more and more replaced by GPT
partitioning.

Allow defining a partition type GUID identifying the partition to load
main U-Boot from.

To avoid using #ifdef in the implementation:

* introduce accessors for fields of struct disk_partition
* provide a macro IF_ENABLED

v3:
	avoid usage of #ifdef
v2:
	avoid if/endif in Kconfig

The necessity of the Kconfig setting was discussed in
https://lore.kernel.org/u-boot/20230216152956.130038-1-heinrich.schuchardt@canonical.com/

Heinrich Schuchardt (3):
  disk: accessors for conditional partition fields
  kconfig: new macro IF_ENABLED()
  spl: allow loading via partition type GUID
