[PATCH 01/17] Add LLVM Morello compiler support

by Pawel Zalewski

Add a native LLVM Morello cross compiler and a native LLVM that will build it. Add class to be inherited by users of LLVM Morello compiler, this class is required as the inital commit does not provide a proper Yocto Morello toolchain.

[PATCH 00/17] *** Initial Yocto support for Morello ***

by Pawel Zalewski

This series of patches forms the inital support for the Morello hardware in Yocto. For limitations and instructions to build refer to the README.md NB The kas scripts will pull meta-morello that is hosted @ TGP repo, not what these patches provide, although these are almost equal. To-do list: - create clang-morello toolchain, follow the guide here http://www.openembedded.org/wiki/Adding_a_secondary_toolchain and move llvm-morello to its own layer * can try append meta-clang instead * can try to use precomipled external toolchain like here https://github.com/MentorEmbedded/meta-sourcery/ instead * thus there are 3 paths to explore forward for the toolchain, Yocto expects target_prefixed toolchain binaries - be considerate of incoming purecap GNU toolchain (related to the above toolchain problem) - sort out the packaging for llvm-morello-compiled packages (related to the above toolchain problem) Pawel Zalewski (17): Add LLVM Morello compiler support Add initial Morello machines and layer config Add scp firmware Add trusted-firmware-a Add UEFI Add grub Add board firmware image Add Morello Linux kernel Add musl libc Add busybox Add libarchcap Add elf patcher Add simple purecap application Add gen-init-cpio Add Linux image Add kas scripts Add README.md -- 2.34.1
