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

2698 the documented boot protocol using a device tree.

2700 Beware that there is very little in terms of protection against
2701 this option being confused by leftover garbage in memory that might
2702 look like a DTB header after a reboot if no actual DTB is appended
2703 to vmlinux.bin. Do not leave this option active in a production kernel
2704 if you don't intend to always append a DTB.

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.
2801
2802 Say Y here if you are building a kernel for an EISA-based machine.
