This is a recently added warning (see
) that tells you that you are trying
to use a payload which would overlap the parts of coreboot that are
loading it (risking random corruption errors and such). The fix is to
link your payload to a different base address which does not overlap
the POSTRAM_CBFS_CACHE region in the memlayout.ld of your
Which board are you building for and which payload are you trying to use?
