1824 Loongson 2F03 and later have fixed these issues and no workarounds
1825 are needed. The workarounds have no significant side effect on them
1826 but may decrease the performance of the system so this option should

3106 The Extended Industry Standard Architecture (EISA) bus was
3107 developed as an open alternative to the IBM MicroChannel bus.
3108
3109 The EISA bus provided some of the features of the IBM MicroChannel
3110 bus while maintaining backward compatibility with cards made for
3111 the older ISA bus. The EISA bus saw limited use between 1988 and
3112 1995 when it was made obsolete by the PCI bus.
3113
3114 Say Y here if you are building a kernel for an EISA-based machine.
3115
3116 Otherwise, say N.
