Also personally I'm not a fan of patches that touch SoC and board files with a commit message that only mentions the SoC, as is frequently done for IDP boards. Why not split this in (at least) two, one for adding the missing memory regions to the SoC, and one for the IDP. > Add missing regions and remove unused regions from the reserved memory > map, as described in version 1. What is this 'version 1'?

I'll just drop it when I re-spin the series since it doesn't add much value.

So including information about where those numbers came from is useful, even if it's referencing a version of a document that's not public. Regards, Bjorn
