Haiying Wang - Dec. 1, 2010, 4:17 p.m.
From: Haiying Wang <Haiying.Wang@freescale.com>

P1021 has some QE pins which need to be set in pmuxcr register before using QE
functions. In this patch, pin QE0 and QE3 are set for UCC1 and UCC5 in Eth mode.
QE9 and QE12 are set for MII management. QE12 needs to be released after MII
access because QE12 pin is muxed with LBCTL signal.

P1021MDS has to load the microcode from NAND flash, this patch defines
misc_init_r() for loading ucode and initializing qe.
