I've been thinking about fallback to using fwname from the gpulist table, but I think I don't really like the idea. The failure mode for not falling back to $firmware/qcom/$fwname is pretty safe.. you simply don't get gpu accel, but display and everything else works, so you can boot up far enough to see what the problem is and fix it. But the failure mode if, with some device's scm fw doesn't report incorrectly signed zap fw, is pretty catastrophic (insta-reboot, which can be hard to debug on phone/laptop without debug uart). Since we haven't pushed the test-key signed qcom/sdm835/a630_zap.mbn to linux-firmware yet, I think this is a good time to make this switch for a6xx. For a530 devices, maybe we hold of adding firmware-name to dt until linux-firmware gains a qcom/msm8996/a530_zap.mbn (which would be a good time to switch to the packed .mbn instead of split .mdt + .b0* files).. or just not specify a firmware-name for device using test-key signed zap and fallback to adreno_request_fw() and the existing path. Fortunately zap is not used prior to a5xx, so we mainly just need to care about backwards compat for a530.
