From 8e30a9a299ca30b6c4072c2182238d5f5dd1590d Mon Sep 17 00:00:00 2001 From: Vitaly Bordug Date: Wed, 24 May 2006 21:40:18 +0400 Subject: [PATCH] ppc32 CPM_UART: various fixes for pq2 uart users This fixes various odd things that missed update together with cpm_uart platform_device move. Unified resources names, restructurisation, etc. Also, addressed issue with recent phys/virt translation rework. Being cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was used to treat console buffer descriptor mapping 1:1 (as in CPM1 case), which is definitely wrong.
