Subject: [PATCH v3 0/6] 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.

Peter De Schrijver (4):
  dt-bindings: mailbox: tegra: Document Tegra264 HSP
  dt-bindings: Add bindings to support DRAM MRQ GSCs
  dt-bindings: memory-region property for tegra186-bpmp
  firmware: tegra: bpmp: Add support for DRAM MRQ GSCs

Stefan Kristiansson (2):
  mailbox: tegra: add support for Tegra264
  soc: tegra: fuse: add support for Tegra264

Changes in v2:

- Added signoff messages
- Updated bindings to support DRAM MRQ GSCs
- Split out memory-region property for tegra186-bpmp
- Addressed sparse errors in bpmp-tegra186.c

Changes in v3:

- Add #address-cells = <2> and #size-cells = <2> to
  nvidia,tegra264-bpmp-shmem binding example.
