of FLASH. Since it runs out of FLASH, we have removed the need for bounce buffer support. that in turn rips out all kinds of stuff, so it is now simpler. We're ripping out all the checksum stuff -- lar does that. lar.c has some debug prints removed. elfboot.c has some mods, but elfboot.c is going away. cachemain.c has a few mods for using newelfboot. Makefile reflects these changes. Not tested, I'm going to bed though, so here you are. Signed-off-by: Ronald G. Minnich <rminnich@gmail.com> Acked-by: Ronald G.
