    x86/efi: Consolidate region mapping logic · ab72a27d
    Matt Fleming authored
    EFI regions are currently mapped in two separate places. The bulk of
    the work is done in efi_map_regions() but when CONFIG_EFI_MIXED is
    enabled the additional regions that are required when operating in
    mixed mode are mapping in efi_setup_page_tables().
    
    Pull everything into efi_map_regions() and refactor the test for
    which regions should be mapped into a should_map_region() function.
    Generously sprinkle comments to clarify the different cases.
