From 1de55ef105f9e00ea313c91679fed6560c63f447 Mon Sep 17 00:00:00 2001 From: Stephan Linz Date: Thu, 24 Nov 2011 12:32:52 +0000 Subject: [PATCH] microblaze: usable uart16550 for big endian systems As a result of the commit 6833260 the uart16550 driver is broken for Microblaze big endian systems, because of the missing 3 byte offset. Other than as described, not all U-Boot BSP will treat properly the 3 byte offset. This why prefer to mask out the 3 byte offset in general and setup correct _REG_SIZE value depending on edianess.
