You add this config option here, named generically, but then make it
depend on BGP. =A0It sees it should be named BGP_L1_WRITETHROUGH, and the=

You add an identical option down here. =A0Confused.

Yeah, this was copied from the original patches and it confused me as
well, but I had never
modified Kconfig.cputype before so I wasn't sure if there were some
weird rules.  I'm happy
to remove the vestigial one and make the changes you suggest to make
the naming BGP
specific.
