1826 Loongson 2F03 and later have fixed these issues and no workarounds
1827 are needed. The workarounds have no significant side effect on them
1828 but may decrease the performance of the system so this option should

3118 The Extended Industry Standard Architecture (EISA) bus was
3119 developed as an open alternative to the IBM MicroChannel bus.
3120
3121 The EISA bus provided some of the features of the IBM MicroChannel
3122 bus while maintaining backward compatibility with cards made for
3123 the older ISA bus. The EISA bus saw limited use between 1988 and
3124 1995 when it was made obsolete by the PCI bus.
3125
3126 Say Y here if you are building a kernel for an EISA-based machine.
3127
3128 Otherwise, say N.
