What is your concern?

Hence, there is no way for a user to enable this directly. 'select EISA' is the only way to enable it. git grep 'select EISA' gave no hit. So, we can say it is dead. > - ---help--- > - The Extended Industry Standard Architecture (EISA) bus was > - developed as an open alternative to the IBM MicroChannel bus. > - > - The EISA bus provided some of the features of the IBM MicroChannel > - bus while maintaining backward compatibility with cards made for > - the older ISA bus.

The difference between arm and powerpc is the presence of help. You fold the powerpc change in 9/9. -- Best Regards Masahiro Yamada
