[PATCH v4 0/33] Secure Boot refactoring / signed PMU firmware support for GM20B
This revision includes initial signed PMU firmware support for GM20B
(Tegra X1). This PMU code will also be used as a basis for dGPU signed
PMU firmware support.
With the PMU code, the refactoring of secure boot should also make
more sense.
ACR (secure boot) support is now separated by the driver version it
originates from. This separation allows to run any version of the ACR
on any chip,
