I think it would be difficult to use system_rev for this purpose as some
boards I know about are using this field to pass a board/PCB revision from
U-Boot to the kernel.
After spending a short look through documentation in kernel and U-Boot
I did not find any hint whether this was the indended usage of this field.
I would rather argue about introducing a new line
"SoC revision: ..." as this is the revision you want to pass to user-space.
The lines "Revision" and "Serial" should IMHO left
alone for usage by board vendors.
BR, Michael
