Well, this switch itself is generic. Theres no armisms in the machine
opt itself.

As for architectures, I can speak for Microblaze and the PPC
bootloader for virtex_ml507. The DTB will blob in regardless of
whether its an elf or not, so no is_linux switch is needed there for
my Linux elfs. There is no functional difference between linux and not
linux in those bootloaders.
