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].
