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

2703 Beware that there is very little in terms of protection against
2704 this option being confused by leftover garbage in memory that might
2705 look like a DTB header after a reboot if no actual DTB is appended

2797 The Extended Industry Standard Architecture (EISA) bus was
2798 developed as an open alternative to the IBM MicroChannel bus.
2799
2800 The EISA bus provided some of the features of the IBM MicroChannel
2801 bus while maintaining backward compatibility with cards made for
2802 the older ISA bus. The EISA bus saw limited use between 1988 and
2803 1995 when it was made obsolete by the PCI bus.
2804
2805 Say Y here if you are building a kernel for an EISA-based machine.
