852 This option supports all of the Octeon reference boards from Cavium
853 Networks. It builds a kernel that dynamically determines the Octeon
854 CPU type and supports all known board reference implementations.
855 Some of the supported boards are:
856 EBT3000
857 EBH3000
858 EBH3100
859 Thunder
860 Kodama
861 Hikari
862 Say Y here for most Octeon reference boards.

2794 The Extended Industry Standard Architecture (EISA) bus was
2795 developed as an open alternative to the IBM MicroChannel bus.
2796
2797 The EISA bus provided some of the features of the IBM MicroChannel
2798 bus while maintaining backward compatibility with cards made for
2799 the older ISA bus. The EISA bus saw limited use between 1988 and
2800 1995 when it was made obsolete by the PCI bus.

2802 Say Y here if you are building a kernel for an EISA-based machine.
