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.

746 This option enables the workaround for the 430973 Cortex-A8
747 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
748 interworking branch is replaced with another code sequence at the

750 to physical address re-mapping, Cortex-A8 does not recover from the

752 executing the new code sequence in the incorrect ARM or Thumb state.
753 The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
754 and also flushes the branch target cache at every context switch.
755 Note that setting specific bits in the ACTLR register may not be
756 available in non-secure mode.

939 This option allows for the kernel to be compiled using the latest
940 ARM ABI (aka EABI). This is only useful if you are using a user
941 space environment that is also compiled with EABI.
942
943 Since there are major incompatibilities between the legacy ABI and
944 EABI, especially with regard to structure member alignment, this
945 option also changes the kernel syscall calling convention to
946 disambiguate both ABIs and allow for backward compatibility support
947 (selected with CONFIG_OABI_COMPAT).
948
949 To use this you need GCC version 4.0.0 or later.

958 intercept syscalls that have structure arguments which layout
959 in memory differs between the legacy ABI and the new ARM EABI
960 (only for non "thumb" binaries). This option adds a tiny
961 overhead to all syscalls and produces a slightly larger kernel.
962 If you know you'll be using only pure EABI user space then you
963 can say N here. If this option is not selected and you attempt
