PS3, Line 840: This top aligns files of type bootblock, assuming that only x86 uses those
> Instead of making this assumption, maybe add a Kconfig option that's selected by x86?  Up to you.

Would --xip not achieve the same without needing this extra code. That should do it for Intel.

I'm not exactly sure how that works for newer AMD systems. Isn't the bootblock cbfs file unnecessary here as the it's embedded inside the PSP image?
