I've seen only now that BR2_sh4 stands only for:
"sh4 (SH4 little endian)"
Here I've meant to make it default y when any BR2_sh4* is selected.
But at this point I would use BR2_sh since if we have that selected
then all BR_sh4* cases are included and no other BR2_sh* is present.

Can you please modify according to that?

Thanks a lot
Kind regards
