In normal way, you can find GIC base address on datasheet as "0x38000000".
But we need to use in Linux is "0x39000000", but it is not indicated, and
there is no hint about it. You can find it in tons of attached documents
as only 1 line.
Indeed the person who can get X5H datasheet is limited, but I believe
that it doesn't mean hint-comment is not useful though.
Thank you for your help !!
Best regards
