Corellium: How we ported Linux to the M1

The Corellium blog is carrying a description of how the Linuxport to the Apple M1 processor was done. "Many components of theM1 are shared with Apple mobile SoCs, which gave us a good runningstart. But when writing Linux drivers, it became very apparent hownon-standard Apple SoCs really are. Our virtual environment is extremelyflexible in terms of models it can accommodate; but on the Linux side, the64-bit ARM world has largely settled on a well-defined set of buildingblocks and firmware interfaces - nearly none of which were used on theM1."
