The following patch has some parts that still need approval, i.e.
* Makefile.in (TEXI_GCC_FILES): Add avr-mmcu.texi.
* doc/avr-mmcu.texi: New auto-generated file.
* doc/invoke.texi (AVR Options): Include avr-mmcu.texi in order
to document all valid -mmcu= arguments.

The avr-specific part is already approved:

> This patch adds a new file ./gcc/doc/avr-mmcu.texi that lists all valid

> Up to now, there is no complete list of -mmcu= options, and a list is
