[Freedreno] [PATCH v2 0/6] qcom: add OCMEM support

[Brian Masney]

This patch series adds support for Qualcomm's On Chip MEMory (OCMEM)
that is needed in order to support some A3xx and A4xx based GPUs
upstream. This is based on Rob Clark's patch series that he submitted
in October 2015 and I am resubmitting updated patches with his
permission. See the individual patches for the changelog.

This was tested with the GPU on a LG Nexus 5 (hammerhead) phone and
this will work on other msm8974-based systems. For a summary of what
currently works upstream on the Nexus 5, see my status page at
https://masneyb.github.io/nexus-5-upstream/.
