From 5093bb965a163fe288c3e5db0275165f86c895c2 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Fri, 23 May 2008 20:39:06 +0400 Subject: powerpc/QE: switch to the cpm_muram implementation This is very trivial patch. We're transitioning to the cpm_muram_* calls. That's it. Less trivial changes: - BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_* prototypes; - qe_muram_dump was unused and thus removed; - added some code to the cpm_common.c to support legacy QE bindings (data-only node name). - For convenience, define qe_* calls to cpm_*. So drivers need not to be changed.

It might not be initialized properly when called from udbg_putc_cpm(), so (recursively) call udbg_putc_cpm() directly.
