To me my biggest kvetch about the risc-v effort was the lack of
additional on-chip IP support, which,
lacking compatible busses and so on, was going to limit multiple
generations of chips to just what could be developed afresh. Even
"simple" IP blocks like usb support take time. While I really lik= e
"chisel" as a design language, it is far behind what arm and inte= l
use. But: With the mips licensees scrambling to reuse their IP,
somehow, and move to risc-v, I think this architecture has an ever
increasing chance of success.

It's been a really good couple of months for open source this or that.
I keep hoping someone will seriously fund
https://github.com/open-sd= r/openwifi  as well, for, in order to handle
the complexities of 802.11n and beyond, a co-processor with some
serious oomph, and a well designed piece of open firmware, is needed.
