I assume the vendor variant, because your patch doesn't match what I saw
in U-Boot mainline.

I guess your tool (U-Boot?) would generate the output I want with:

	md.l 0x43fac000 353

(i.e. 353 32bit words, that are all the iomux registers)

Which version do you have? How is it broken? Did you configure AIPS to
allow non-privileged access to the peripherals? Our internal
documentation tells you have to set (in the boot loader) the following
registers to 0:

	0x43f00020 0x43f00024 0x43f00028 0x43f0002c
	0x43f00040 0x43f00044 0x43f00048 0x43f0004c 0x43f00050

After that memtool works fine for me in Linux.

Best regards
Uwe
