Subject: drm/nouveau/secboot: add GP10B support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59d5592d3bf2e70b9c56212cf5c9f1bfab6f0147;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/nouveau/secboot: add GP10B support

GP10B's secboot is largely similar to GM20B's. Only differences are MC
base address and the fact that GPCCS is also securely managed.
