From 83af919e0f239e87bc644a2c932b9cebf5771380 Mon Sep 17 00:00:00 2001 From: Jochen Friedrich Date: Mon, 24 Sep 2007 19:13:46 +0200 Subject: [POWERPC] Fix copy'n'paste typo in commproc.c The powerpc version of commproc.c exports cpm_dpram_addr twice and cpm_dpram_phys not at all due to a typo.

As there usually is a 1:1 MMU map of the IMMR area, this is often not noticed. However, cpm_dpram_phys assumes this iomapped virtual memory and returns garbage on the 1:1 mapped memory causing CPM1 uart console to fail. This patch fixes the problem (copied from the powerpc tree).

On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't be used for arithmetric compare operations with virtual addresses returned by cpm_dpram_addr. This patch changes the assignment to use cpm_dpram_addr as well, like in cpm_uart_cpm2.h.
