Message-Id: <1391725484-6673-4-git-send-email-galak@codeaurora.org>

Subject: [PATCH v3 3/5] 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.
