https://svnweb.freebsd.org/base/release/11.1.0/sys/arm/conf/

does not have a GENERIC configuration file. Nor does:

https://svnweb.freebsd.org/base/stable/11/sys/arm/conf/

GENERIC for TARGET_ARCH=armv6 is newer and is only in/for:

https://svnweb.freebsd.org/base/head/

so far. I do not know if it will ever be merged back to
stable/11 or not.

I think that the above reply was implicitly referencing
head (12) only for GENERIC, not even stable/11 . So
source code based on:

https://svnweb.freebsd.org/base/head/
