From 02b08045a0306c38131c6d7155c4034a775d40b1 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 28 Sep 2010 16:04:14 +1000 Subject: microblaze: Add support for little-endian Microblaze Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.
