If it's too much work to make EFI_LOADER work on these platforms, I guess it's ok to disable it just for them. Given how dated they are, chances are pretty slim that enabling EFI_LOADER by default will give us a U-Boot copy on the device that supports it straight from the factory ;). However, I would ideally prefer to see that happen in the respective defconfigs, not in Kconfig.
