TI K3 J721s2 uses the same GPU, and firmware is available in upstream
linux-firmware. The firmware is loaded, but fails to boot:
powervr fd000000.gpu: [drm] loaded firmware
powervr/rogue_36.53.104.796_v1.fw
powervr fd000000.gpu: [drm] FW version v1.1 (build 6976702 OS)
powervr fd000000.gpu: [drm] *ERROR* Firmware failed to boot
