To give some background on why I think it is not:

The contents of the files are all static, so you can generate them
at compile time from an init function that is then discarded. When you
build a kernel for many different SoCs, you only need the pointers
at run-time, while your approach means that the kernel image will
have to keep all the functions for every SoC that is built in.

Also, in many cases, the strings themselves will be static and not
taken from a specific register.

A Signed-off-by is not appropriate because I was not involved in sending
the patch but in reviewing it. I can give you a 'Reviewed-by', which
is the appropriate reply in this case.

Ok.
