The Freescale P1022 has a unique pin muxing "feature" where the DIU =

When the DIU is enabled, the bulk of the local bus is disabled, =

preventing

access to memory-mapped devices like NAND flash and the pixis FPGA.

Therefore, if the DIU is going to be enabled, then memory-mapped =

devices on

the localbus, like NAND flash, need to be disabled.

This patch is similar to "powerpc/85xx: p1022ds: disable the NOR flash =

node

if video is enabled", except that it disables the NAND flash node =

instead.

This PIXIS node needs to remain enabled because it is used by platform =

code

to switch into indirect mode.
