Hi Manivannan
Interesting combination of CPUs.

Looking forward, what sharing do you expect at the device tree level?
Looking at
https://sophon-file.bitmain.com.cn/sophon-prod/drive/18/11/06/19/BM1880%20product%20brief%20V0.04_Chinese%20versionV0.06.pdf
it appears all the devices can be shared between the CPUs. So do you
plan to have a shared .dtsi file somewhere?
Is ARCH_BITMAIN going to be both ARM64 and RISC-V?
Thanks
Andrew
