	---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.

	  The workaround enables the BTB/BTAC operations by setting ACTLR.IBE

	  Note that setting specific bits in the ACTLR register may not be
	  available in non-secure mode.

	  in the ACTLR register. Note that setting specific bits in the ACTLR
	  register may not be available in non-secure mode.

	   They are architecturally defined to behave as the execution of a

	   both performing to the same memory location. This functionality
	   is not correctly implemented in PL310 as clean lines are not
