    powerpc: introduce early_get_first_memblock_info · b27652dd
    Kevin Hao authored
    For a relocatable kernel since it can be loaded at any place, there
    is no any relation between the kernel start addr and the memstart_addr.
    So we can't calculate the memstart_addr from kernel start addr. And
    also we can't wait to do the relocation after we get the real
    memstart_addr from device tree because it is so late. So introduce
    a new function we can use to get the first memblock address and size
    in a very early stage (before machine_init).
