How do you reckon this constitutes a limit?
handle_cmdline_files() calls efi_high_alloc() with that limit. I'm still
trying to understand all the details myself, but apparently our firmware and
initrd need to fit within the first 512MB because of dram_base + SZ_512M.
When we change "dram_base + SZ_512M" to "~0", everything works.
