The Morello architecture is an experimental extension to Armv8.2-A, which extends the AArch64 state with the principles proposed in version 7 of the Capability Hardware Enhanced RISC Instructions (CHERI) ISA. The Morello Platform (soc) and the Fixed Virtual Platfom (fvp) share some functionalities that have conveniently been included in morello.dtsi to avoid duplication. Introduce morello.dtsi. Note: Morello fvp will be introduced with a future patch series.

+[...] Not sure if you are not seeing these warnings from DTC. Looks pretty clear to me. May be you missed or using some old DTC. I don't know why though. If you agree, I can patch it up with below patch and no need to repost: morello.dtsi:227.38-272.5: Warning (simple_bus_reg): /soc/interrupt-controller@2c010000: simple-bus unit address format error, expected "30000000" morello.dtsi:296.23-313.5: Warning (simple_bus_reg): /soc/sram@45200000: simple-bus unit address format error, expected "6000000" morello.dtsi:227.38-272.5: Warning (simple_bus_reg): /soc/interrupt-controller@2c010000: simple-bus unit address format error, expected "30000000" morello.dtsi:296.23-313.5: Warning (simple_bus_reg): /soc/sram@45200000: simple-bus unit address format error, expected "6000000" Regards, Sudeep -->8
