From 0b23780ff02bdbec46fac1fe4151e2ebf1eae881 Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Wed, 29 Oct 2014 17:56:22 +0200 Subject: [PATCH] arm: mx6: cm_fx6: detect 1GB DRAM correctly on solo The 1GB DRAM configuration on mx6 solo uses 2 chip selects, but the code tests 1GB DRAM configuration as if it is all present on one chip select, and thus cannot see the full range of available memory. Refactor the check to detect 1GB DRAM correctly.
