[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. Signed-off-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
