So here is the full diff with all architecture makefiles that may
be affected.
I have done a build release on amd64. Boot loader on i386, armv7,
arm64, macppc compiles and links. hppa, landisk, octeon is just a
guess what should be done.
Is more testing needed?

This strtoll() version has less error checking, does not work with
addresses >= 0x8000, but reduces stripped boot size by
64 bytes.

why not use strtol here?
hexdump in boot loader
Hi,
I am currently debugging an UEFI boot problem. A hexdump in the
boot loader would be convenient.
boot> hexdump 0x10 20
0010 53 ff 00 f0 54 ff 00 f0 53 ff 00 f0 53 ff 00 f0 |S...T...S...S...|
0020 a5 fe 00 f0 ||
0024
Do we want such a feature?
If so, I would adapt the other's architectures Makefiles.
