e5bd94b6b0 Now that exit is __dead2, we need to tag ub_exit() as __dead2. To do 
that, we have to put a while (1); after the syscall that will never
return to fake out the compiler....

433b21d9f0 stand/fdt: Consistently apply fdt_overlays 
Overlays were previously not applied when U-Boot provides FDT or EFI
provides FDT, only when we load FDT from /boot/dtb given name from U-Boot.

Make all three paths lead to loading fdt_overlays and applying them, so that
fdt_overlays can be expected to Just Work.

7f3384f4af Interact is always called with NULL. Simplify code a little by 
removing this argument, and expanding when rc is NULL. This
effectively completes the back out of custom scripts for tftp booted
loaders from r269153 that was started in r292344 with the new path
tricks that obsoleted it.

423586ee2d When building for arm arches, set PKGALIGN to the max cache line size 
supported by the arch, to meet u-boot's requirement that I/O be done
in cache-aligned chunks.

f097f35b37 Move some more common stuff up to Makefile.inc. In particular, the no 
simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.
