Subject: [PATCH 8/8] char/genrtc: disallow building on mn10300

The genrtc driver serves no purpose on mn10300 because it drives the
same hardware as the original rtc.c driver, and the newer rtc-generic.c
or rtc-cmos.c drivers on architectures that use the asm-generic/rtc.h
header.

I assume it was initially only added for completeness when the
mn10300 port was done, but the older rtc.c driver was always used
instead.

It would be nice to change the architecture to use the rtc-cmos driver
next, and remove support for the old rtc driver as well.
