From efdf72ad5c42b529286a1991f51badb030043719 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Sat, 12 Feb 2011 18:22:49 -0800 Subject: ARM: tegra: Add external memory controller driver The frequency memory bus on Tegra can be adjusted without disabling accesses to memory by updating the memory configuration registers from a per-board table, and then changing the clock frequency. The clock controller and memory controller have an interlock that prevents the new memory registers from taking effect until the clock frequency change.
