From 3af391e862bd580b9748b383c808d5ed63d52c1b Mon Sep 17 00:00:00 2001 From: mpoojary Date: Tue, 28 Sep 2021 11:56:36 +0000 Subject: gpu: nvgpu: adds support for ACR dbg/prod. ACR ucode is encrypted using different keys for prod/dbg boards. This change adds a check to select ACR ucode based on board type. Note: This support is added for t18x. In the sub-sequent CL, support for T210 will be added and since ACR binaries are different for gp10b and gm20b, a new ACR init function is created for gp10b to accept new ACR prod/dbg binaries.
