From d214602804a85e5da68b745ae69d9beaa5bedc93 Mon Sep 17 00:00:00 2001 From: Jochen Friedrich <jochen@scram.de> Date: Mon, 24 Sep 2007 19:15:43 +0200 Subject: [PATCH] [POWERPC] Fix cpm_uart driver for cpm1 machines in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp. 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.
