[PATCH] ofmem: Fix and enable ofmem_claim() trace output
by Andreas Färber 03 Oct '10

03 Oct '10

A printk statement was commented out and there were format string mismatches for ppc target. Use OFMEM_TRACE to more easily enable/disable it and use FMT_ucellx as in other trace output. Note that this changes the alignment from decimal to hexidecimal notation.
