[PATCH 2/4] drm/imagination: Make the MIPS firmware headers arch-independent
Alexandru Dadu
alexandru.dadu at imgtec.com
Wed Oct 14 01:13:08 PDT 2026
From: Alessio Belle <alessio.belle at imgtec.com>
While this header is specific to Rogue, rename it and its contents
anyway with arch-independent prefixes for consistency with the other
firmware processor headers.
