    fdt: prevent clearing memory node if there are no banks · 5c1cf89f
    Andre Przywara authored
    Avoid clearing the reg property in the memory DT node if no memory
    banks have been specified for a board (CONFIG_NR_DRAM_BANKS == 0).
    This allows boards to let U-Boot skip the DT memory tinkering in case
    other firmware has already setup the node properly before.
    This should be safe as all callers of fdt_fixup_memory_banks that use
    a computed <banks> value put at least 1 in there.
    Add some documentation comments to the header file.
