From f9040550bef6f05e68af029f11c371a318220a05 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 19 Mar 2014 01:17:21 +0000 Subject: [PATCH] ARM: l2c: tegra: remove cache size override The cache size should already be present in the L2 cache auxiliary control register: it is part of the integration process to configure the hardware IP. Most platforms get this right, yet still many cargo-cult program, and assume that they always need specifying to the L2 cache code. Remove them so we can find out which really need this.
