This patchset adds architecture support to Linux for C-SKY's 32-bit embedded CPU cores and the patches are based on linux-4.16-rc5. There are two ABI versions with several CPU cores in this patchset: ABIv1: ck610 (16-bit instruction, 32-bit data path, VIPT Cache ...) ABIv2: ck807 ck810 (16/32-bit variable length instruction, PIPT Cache ...) More information: http://en.c-sky.com I'm from Hangzhou,China C-SKY Microsystems and responsible for C-SKY Linux port. My development repo is github.com/c-sky/csky-linux and use buildroot as our CI-test enviornment. "LTP, Lmbench, uclibc-ng-test ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines You can try C-SKY linux in a few steps: $ git clone https://github.com/c-sky/buildroot.git $ cd buildroot $ make qemu_csky_ck807_uclibc_bt_defconfig $ make It will download "linux uclibc-ng gcc binutils qemu busybox" source code and build them into one image. How to run, See: https://github.com/c-sky/buildroot/blob/master/board/qemu/csky/readme.txt I've finished uClibc-ng.org upstream and "gcc glibc binutils qemu ..." upstream is on going and the source code is here: https://github.com/c-sky It's my first patchset to linux and any feedback is welcome :) Guo Ren (19): csky: Kernel booting csky: Exception handling and syscall csky: Cache and TLB
