Thanks, David, ever so much for the patch. I'd played with Jedec too.
I actually got amd_flash.c to seemingly work on its own -- just
tested with "mtd_debug read/write ..." My hacked amd_flash.c prints:
Physically mapped flash: Found 1 x 4MiB AMD AM29LV800BT (*4) at 0x0
^^^^
Yeah!
I'd prefer to use your version, will give it a try...
