That didn't work too well here. While it did correctly detect some
instances:
zImage size (8008200) disagrees with linked size (8008192)
it also misdetected others:
zImage size (13348808) disagrees with linked size (-928003328)
It seems to suggest that _magic_end - _magic_start = 0xc8afcb00.
zImage size is 0xcbafc8. That points at the addresses output by
"nm" being dependent on the endian-ness of the image, which to
me seems utterly insane.
I wouldn't be surprised if that is toolchain version dependent
as well.
IMHO, our toolchain is a mess!
