Yeah, Raspberry Pi has done a great job with documentation and SDKs for SBC and their line of MCU. I don't think Raspberry Pi would have been started outside the margins of the smartphone market economies of scale. Sure RPi are pretty big now but the smartphone market created a world where low power CPUs and a lot of other components are available at all. My recollection is that as RPi got further away from standard chips, they struggled balancing retail availability while servicing their commercial contracts. RISC-V, to me, seems more of an IP hedge for chipmakers who may find themselves constrained in designs or distribution in the future because the IP is controlled by potentially unfriendly companies or jurisdictions. Sure, there are some licensing fees/certifications that are friction, but the goal is independence even at the cost of redundant effort in chip and compiler design.
