From 8fc1b0f87d9fcc7f05873c70b3003328c3d7defa Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 21 Jan 2014 17:14:10 -0600 Subject: [PATCH] ARM: qcom: Split Qualcomm support into legacy and multiplatform Introduce a new mach-qcom that will support SoCs that intend to be multiplatform compatible while keeping mach-msm to legacy SoC/board support that will not transition over to multiplatform. As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over to mach-qcom.
