What I did

  • Added two patches under patches-sonic/ that introduce NVIDIA SPC6 BMC device trees for ASPEED AST2700:
    • A1: aspeed-nvidia-spc6-a1-bmc.dts with shared aspeed-nvidia-spc6-a1-bmc-core.dtsi, and a Makefile rule to build aspeed-nvidia-spc6-a1-bmc.dtb.
    • A2: aspeed-nvidia-spc6-bmc.dts with shared aspeed-nvidia-spc6-bmc-core.dtsi, plus nvidia-ast27xx-irot.dtsi and nvidia-ast27xx-sunda.dtsi, and a Makefile rule to build aspeed-nvidia-spc6-bmc.dtb.
  • Registered both patches in patches-sonic/series (Aspeed section).

Why I did it

  • Enable SONiC Linux kernel builds to produce the correct DTBs for NVIDIA SPC6 BMC hardware on AST2700 A1 and A2 silicon variants so the platform can boot and expose the expected hardware description.

How I verified it

  • Applied patches-sonic/series and confirmed the tree contains the expected new DTS/DTI files and Makefile entries.
  • Verified on NVIDIA BMC hardware (SPC6 AST2700 A1/A2 images built from these DTBs boot and behave as expected on the target BMC).
