Subject: [PATCH v4 00/10] riscv: add initial support for SpacemiT K1
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].
As previous discussion in patch v1[4], maintainer expect more basic drivers
ready before really merging it, which would be fine. For other follow-up patches,
that are clk, pinctrl/gpio, reset.. My current goal would target at a headless
system including SD card, emmc, and ethernet.
In this series, the uart node has no 'fifo-size', 'tx-threshold' property populated,
will add them once this patch is resolved, see thread [5]
P.S: talked to Yangyu, I will help and take care of this patch series, thanks
