    efi: Implement generic support for the Memory Attributes table · 10f0d2f5
    Ard Biesheuvel authored
    This implements shared support for discovering the presence of the
    Memory Attributes table, and for parsing and validating its contents.
    
    The table is validated against the construction rules in the UEFI spec.
    Since this is a new table, it makes sense to complain if we encounter
    a table that does not follow those rules.
    
    The parsing and validation routine takes a callback that can be specified
    per architecture, that gets passed each unique validated region, with the
    virtual address retrieved from the ordinary memory map.
