[PPC] Fix cpm_dpram_addr returning phys mem instead of virt mem
cpm_dpram_addr returns physical memory of the DP RAM instead of iomapped virtual memory. 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). Signed-off-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
