Sending things in a smaller chunks since it makes their reviewing easier. This part part 2/3 of the secboot refactoring/PMU command support patch series. Part 1 was the new falcon library which should be merged soon now. This series is mainly a refactoring/sanitization of the existing secure boot code. It does not add new features (part 3 will). Secure boot handling is now separated by NVIDIA

This is a rework of the secure boot code that moves the building of the blob into its own set of source files (and own hooks), making the code more flexible and (hopefully) easier to understand as well. This rework is needed to support more signed firmware for existing and new chips. Since the firmwares in question are not available yet I cannot send the code to manage then, but hopefully the

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,

GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result.
