Subject: [PATCH 00/19] C-SKY(csky) Linux Kernel Port
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 :)
