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 [1]. This series adds dts support for the Arm Morello System Development Platform. [1] https://www.morello-project.org/ To simplify the testing a linux tree rebased on 6.14-rc1 is accessible at [2].
