For the most part it mirrors Janne's M3 (t8122) bringup series as it was merged in the 7.2 cycle. This series covers only a minimal amount of hardware, which is useful as a basis for future developments. The hardware added here has remained largely unchanged between the M3 and M4 generations. Most of the changes for bringing these M4 devices into a bootable state have been happening in the m1n1 bootloader, which is no longer responsible for setting the configuration bits (🐔-bits) of the CPU, since these are now set and locked by iBoot. Additionally, SMP boot depends on the idle=nop patches I sent out earlier today, and is still unstable, even with those.
