i feel like if we tried harder, we could automate the -e arg for all
arches. i understand if you don't want to undertake that though.

Yes, this might be possible. I'd guess the symbol name varies between
archs, but that can probably be taken care of.

i think we could avoid the symbol lookup.  if the entry point is set correctly 
in the ELF, we could do:
UIMAGE_ENTRYADDR = $(shell $(READELF) -h vmlinux | \
	awk '$$0 ~ /Entry point address:/ { print $$NF }'

99% sure this would work for Blackfin kernel images ...

This is probably best
left as a follow-on patch though, since it's a behavioral change,
whereas this patch is just consolidation.

of course
