From 9cf12167e909a86fbc4b39cf4cffef4cba40f1b3 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Wed, 23 Jul 2014 16:36:25 +0200 Subject: MIPS: Alchemy: add helpers to access static memory ctrl registers. This patch changes the static memory controller registers to offsets from base, prefixes them with AU1000_ to avoid silent failures due to changed addresses and introduces helpers to access them. No functional changes, comparing assembly of a few select functions shows no differences.
