All MTL and ARL SKUs share the same GSC FW, but the newer platforms are only supported in newer blobs. In particular, ARL-S is supported starting from 102.0.10.1878 (which is already the minimum required version for ARL in the code), while ARL-H and ARL-U are supported from 102.1.15.1926. Therefore, the driver needs to check which specific ARL subplatform its running on when verifying that the GSC FW is new enough for it.
