[Arm-netbook] New Risc-V fully free chip

[Luke Kenneth Casson Leighton]

added the smartphone/tablet scenario, added DDR3, SYS and POWER
pins.... total comes to 290!  that's around 18x18 on a side, maybe
19x19 to make space for routing, which in a BGA form-factor @ 0.8mm
pitch would be a 15x15mm package!

0.8mm deliberately because it's far, far easier to do a PCB with
larger vias, and you can (i think) just about get a 4mil maybe even a
5mil trace in between 0.8mm BGA pads.

cooool :)
