Support for it (and UEFI ) came with their push into servers, they were forced to make the platform a lot less special and more general purpose like x86 traditionally has been.
End user facing hardware is a different matter though, like I know you can boot the Raspberry Pi via UEFI/ACPI (It builds the ACPI tables in the bootloader), but then Apple doesn’t use it at all for their ARM hardware and it uses something closer to a modern OpenFirmware.
