Subject: [PATCH 0/5] firmware: tegra: Add MRQ support for Tegra264

In Tegra264 the carveouts (GSCs) used to communicate between BPMP and
CPU-NS may reside in DRAM. The location will be signalled using reserved
memory node in DT. Additionally some minor updates to the HSP driver are
done to support the new chip.
