Projects - H3 ATF - Arm Trusted Firware

ATF is a Hypervisor that U-Boot cooperates with for all 64 bit ARM systems. Up to now I have tried to just ignore it, but I suspect that the troubles I have had with interrupts on 64 bit ARM may trace to needing to deal with (or at least understand) the ATF.

Full source code is available, so learning all about it does not involve any deep secrets being guarded by chip vendors. Building the ATF for a given chip is quick and easy and virtually all chips have support in the standard ATF distribution.
