Imagination Technologies to design RISC-V cores:
Now better known for its PowerVR embedded GPUs, Imagination Technologies tried to enter the CPU market by purchasing MIPS Technologies and introducing microAptiv, interAptiv, and proAptiv cores in 2012.
It did not end up well, as the company had to sell its MIPS technology a few years later, and the MIPS architecture is now barely supported. But Imagination is now working on getting back into the CPU space by designing RISC-V cores.
[...] a May 2021 report by the Financial Times claims Imagination expects to invest up to $150m over the next two years to target a fresh push into the processor design market, specifically citing the RISC-V architecture.

0xc0000000-0xffffffff is the top 1/4 of 32 bit memory. This range is often reserved for the OS on x86-32 so reserving it for I/O would conflict. Maybe they moved to a high-half design and blocked out 0x80000000-0xbfffffff for the OS?
