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

2693 This is meant as a backward compatibility convenience for those
2694 systems with a bootloader that can't be upgraded to accommodate
2695 the documented boot protocol using a device tree.

2697 Beware that there is very little in terms of protection against
2698 this option being confused by leftover garbage in memory that might
2699 look like a DTB header after a reboot if no actual DTB is appended
2700 to vmlinux.bin. Do not leave this option active in a production kernel
2701 if you don't intend to always append a DTB.

2791 The Extended Industry Standard Architecture (EISA) bus was
2792 developed as an open alternative to the IBM MicroChannel bus.
2793
2794 The EISA bus provided some of the features of the IBM MicroChannel
2795 bus while maintaining backward compatibility with cards made for
2796 the older ISA bus. The EISA bus saw limited use between 1988 and
2797 1995 when it was made obsolete by the PCI bus.
