It's the architectures that can use UEFI to boot - GPT is the UEFI partition format.

PowerPC and S/390 don't boot via UEFI, hence omitted.

CONFIG_EFI_PARTITION defaults to yes since commit 5f6f38dbb0fc8518 ("partitions: enable EFI/GPT support by default") in v3.8, under the premise that GPT is now (2013) commonly used.
Looking at the defconfigs, only some old m68k and MIPS machines, microblaze, and riscv nommu disable it explicitly.

New architectures are added as needed. Nobody requested the ones you mentioned so far. If they support GPT and you need support for them, please send a PR.
