1801 Loongson 2F03 and later have fixed these issues and no workarounds
1802 are needed. The workarounds have no significant side effect on them
1803 but may decrease the performance of the system so this option should
1804 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1805 systems.

2945 This is meant as a backward compatibility convenience for those
2946 systems with a bootloader that can't be upgraded to accommodate
2947 the documented boot protocol using a device tree.
2948
2949 Beware that there is very little in terms of protection against
2950 this option being confused by leftover garbage in memory that might
2951 look like a DTB header after a reboot if no actual DTB is appended
2952 to vmlinux.bin. Do not leave this option active in a production kernel
2953 if you don't intend to always append a DTB.

3061 The Extended Industry Standard Architecture (EISA) bus was
3062 developed as an open alternative to the IBM MicroChannel bus.
3063
3064 The EISA bus provided some of the features of the IBM MicroChannel
3065 bus while maintaining backward compatibility with cards made for
3066 the older ISA bus. The EISA bus saw limited use between 1988 and
3067 1995 when it was made obsolete by the PCI bus.
