Message

Nikolaos Pasaloukos April 25, 2024, 9:15 a.m. UTC

Adds basic support for the Blaize BLZP1600 SoC.
This SoC contains two cores of Cortex-A53 CPUs, one Blaize
Graph Streaming Processor (GSP) and several other IPs.

V3 changes:
 * Removed unnecessary dt-bindings
 * Update SoBs

V2 changes:
 * Update SoBs
 * `make dtbs_check` has no warnings
 * Fix dts names and removed dead code
 * DTS is separated from anything else

Nikolaos Pasaloukos (5):
  dt-bindings: Add Blaize vendor prefix
  dt-bindings: arm: blaize: Add Blaize BLZP1600 SoC
  arm64: Add Blaize BLZP1600 SoC family
  arm64: Add initial support for Blaize BLZP1600 CB2
  arm64: defconfig: Enable ARCH_BLAIZE_BLZP1600

I dunno if you've yet had any comment from Arnd on this series, but I'd
expect that the blaize patches follow the same path via the soc tree as
any other platform. I presume either you or one of the other Blaize guys
on this patchset will be taking care of that, so it would be a good idea
to add a MAINTAINERs entry covering the new arch/arm64/boot/dts/blaize
directory. There should be some more info about some of the expectations
