CPU type identification

[bmarkus]

Unfortunately version 5.10.x of the kernel intentionally doesn't report the real CPU (SoC) model, e.g. 'cat /proc/cpuinfo' is reporting BCM2835 on RPi 3 and 'uname -m' is not usable to distinguish RPi3 and RPi 4, etc.

To get the real SoC model, use the new getrpicpu command introduced in piCore-13.0.1 (32-bit).
