Some of the newer platforms use a bigger RSA key to authenticate the GuC, which is provided to the HW via a ggtt-pinned object instead of mmio. While doing the changes for this I've also spotted an inconsistency in the error status of the fw on init failure, so I've added a path to fix that as well. v2: clarify in comments that the expected RSA size is hardcoded in the bootrom (Matt)
I've confirmed with Matt that he's ok with the updated comment and pushed. Daniele
