[PATCH v1 0/9] riscv: add initial support for SpacemiT K1

[Yangyu Chen]

SpacemiT K1 is an ideal chip for some new extension such as RISC-V Vector
1.0 and Zicond evaluation now. Add initial support for it to allow more
people to participate in building drivers to mainline for it.

This kernel has been tested upon Banana Pi BPI-F3 board on vendor U-Boot
bootflow generated by Armbian SDK[1] and patched OpenSBI[2] to enable
Zicboz, which does not in the vendor dts on its U-Boot. Then successfully
booted to busybox on initrd with this log[3].
