    armv7: Place reset vector + CBFS header + bootblock dynamically
    This replaces hard-coded bootblock offsets using the new scheme.
    The assembler will place the initial branch instruction after BL1,
    skip 2 aligned chunks, and place the remaining bootblock code after.
    It will also leave an anchor string, currently 0xdeadbeef which
    cbfstool will find. Once found, cbfstool will place the master CBFS
    header at the next aligned offset.
    Here is how it looks:
                 0x0000 |--------------|
                        |     BL1      |
                 0x2000 |--------------|
                        |    branch    |
        0x2000 + align  |--------------|
                        |  CBFS header |
    0x2000 + align * 2  |--------------|
                        |   bootblock  |
    TODO: The option for alignment passed into cbfstool has always been
    64. Can we set it to 16 instead?
