commit 535a8af278eb17bbfe1770d067912c0adca67d4d

    snow: Stuff to support building image with BL1
    
    This patch does two things which will take effect in follow-up
    patches:
    1. Add an intermediate Makefile rule for dd'ing BL1 into the
       coreboot.rom pre-image. This is modeled after a similar hack
       for the bd82x6x southbridge.
    2. Add a Kconfig variable, BOOTBLOCK_OFFSET, which will be used to
       pass the bootblock offset into cbfstool.
