(Late) heads-up for new risc-v soc and board

[Janne Rosberg]

Hi all devs,

First of all, it’s nice to be back on (public) NuttX development. It’s been a 
while since last time. 😊

We are doing porting for MicroChip PolarFire Risc-V SoC and Icicle evaluation 
board.
Basic things already works (uart and gpios) so we can boot to nsh.
First PR #3770 is already “pending”

If there is anybody who is working on this SoC please let us know so that we 
can combine our work forces…
But anyway, we continue with peripheral drivers; I2C already done others to 
follow.

This work is was made possible by TII. https://github.com/tiiuae so all PR’s 
are coming from there.

Br,
Janne
