upset me ? no you did not, but what Robert just said verifies what I've been saying all along. All you need is a good uEnv.txt.
I am not an EE by ant stretch of the imagination, but I know I've been "booting" from uSD since at least June last year. So, when i say "I dont care about the schematics" I mean that MAYBE the hardware may be wired that way, but software can and will override( or at least seems this way ). End result, no having to pull x.y.z pin low, or whatever. You just use a config line in uEnv.txt.
