config EISA
	bool
	---help---
	  The Extended Industry Standard Architecture (EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older ISA bus.  The EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the PCI bus.

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

	  Otherwise, say N.

	  to physical address re-mapping, Cortex-A8 does not recover from the
	  stale interworking branch prediction. This results in Cortex-A8
	  executing the new code sequence in the incorrect ARM or Thumb state.
	  The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
	  and also flushes the branch target cache at every context switch.
	  Note that setting specific bits in the ACTLR register may not be
	  available in non-secure mode.

	  This option enables the workaround for the 458693 Cortex-A8 (r2p0)
	  erratum. For very specific sequences of memory operations, it is
	  possible for a hazard condition intended for a cache line to instead
	  be incorrectly associated with a different cache line. This false
	  hazard might then cause a processor deadlock. The workaround enables
	  the L1 caching of the NEON accesses and disables the PLD instruction
	  in the ACTLR register. Note that setting specific bits in the ACTLR
	  register may not be available in non-secure mode.
