[PATCH v7 20/45] drm/amd: Parse both v1 and v2 TA microcode headers using same function
From: Mario Limonciello
Date: Thu Jan 05 2023 - 12:04:23 EST
Several IP versions duplicate code and can't use the common helpers.
Move this code into a single function so that the helpers can be used.
Signed-off-by: Mario Limonciello <mario.limonciello@xxxxxxx>
---
v6->v7:
* Drop tags
* Only set adev->psp.securedisplay_context.context on PSPv12 Renoir and
PSP v10 which matches previous behavior. If it should match for Cezanne
and PSPv11 too we can undo this part of the check.
v5->v6:
* Rebase on earlier patches
