63 The Extended Industry Standard Architecture (EISA) bus was
64 developed as an open alternative to the IBM MicroChannel bus.
65
66 The EISA bus provided some of the features of the IBM MicroChannel
67 bus while maintaining backward compatibility with cards made for
68 the older ISA bus. The EISA bus saw limited use between 1988 and
69 1995 when it was made obsolete by the PCI bus.

757 This option enables the workaround for the 430973 Cortex-A8
758 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
759 interworking branch is replaced with another code sequence at the
760 same virtual address, whether due to self-modifying code or virtual
761 to physical address re-mapping, Cortex-A8 does not recover from the
762 stale interworking branch prediction. This results in Cortex-A8
763 executing the new code sequence in the incorrect ARM or Thumb state.
764 The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
765 and also flushes the branch target cache at every context switch.
766 Note that setting specific bits in the ACTLR register may not be
767 available in non-secure mode.

931 real-time or interactive events by allowing a low priority process to
932 be preempted even if it is in kernel mode executing a system call.

952 space environment that is also compiled with EABI.

954 Since there are major incompatibilities between the legacy ABI and
955 EABI, especially with regard to structure member alignment, this
956 option also changes the kernel syscall calling convention to
957 disambiguate both ABIs and allow for backward compatibility support
