the Makefile claims otherwise ... patch attached to remove sha1.o from mkimage linking since it isnt actually used.
Indeed the Makefile contained a not needed reference.
It is likely we'll need sha1 support in mkimage for the new uImage format. Let's wait with this patch until mkimage extension to the new uImage format is settled down.
I'm not so sure. Maybe it's better to clean up now, and deal with the new image format requirements when we're at it. Please note that the mkimage code has recenty been added to the Linux kernel tree, and there the sha1 reference was also removed. I think it makes sense to keep both in sync...
