79 The Extended Industry Standard Architecture (EISA) bus was
80 developed as an open alternative to the IBM MicroChannel bus.
81
82 The EISA bus provided some of the features of the IBM MicroChannel
83 bus while maintaining backward compatibility with cards made for
84 the older ISA bus. The EISA bus saw limited use between 1988 and
85 1995 when it was made obsolete by the PCI bus.
86

1094 This option enables the workaround for the 430973 Cortex-A8
1095 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
1096 interworking branch is replaced with another code sequence at the
1097 same virtual address, whether due to self-modifying code or virtual
1098 to physical address re-mapping, Cortex-A8 does not recover from the
1099 stale interworking branch prediction. This results in Cortex-A8
1100 executing the new code sequence in the incorrect ARM or Thumb state.
1101 The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
1102 and also flushes the branch target cache at every context switch.
1103 Note that setting specific bits in the ACTLR register may not be
1104 available in non-secure mode.

1109 help
1110 This option enables the workaround for the 458693 Cortex-A8 (r2p0)
1111 erratum. For very specific sequences of memory operations, it is
1112 possible for a hazard condition intended for a cache line to instead
1113 be incorrectly associated with a different cache line. This false
1114 hazard might then cause a processor deadlock. The workaround enables
1115 the L1 caching of the NEON accesses and disables the PLD instruction
1116 in the ACTLR register. Note that setting specific bits in the ACTLR
1117 register may not be available in non-secure mode.

1126 and overwritten with stale memory contents from external memory. The

1835 Say Y to include the NWFPE floating point emulator in the kernel.
1836 This is necessary to run most binaries. Linux does not currently
1837 support floating point hardware so you need to say Y here even if
1838 your machine has an FPA or floating point co-processor podule.
1839
1840 You may say N here if you are going to load the Acorn FPEmulator
1841 early in the bootup.

1847 Say Y to include 80-bit support in the kernel floating-point
1848 emulator. Otherwise, only 32 and 64-bit support is compiled in.
1849 Note that gcc does not generate 80-bit operations by default,
1850 so in most cases this option only enlarges the size of the
1851 floating point emulator without any good reason.
1852
1853 You almost surely want to say N here.

1859 Say Y here to include the FAST floating point emulator in the kernel.
1860 This is an experimental much faster emulator which now also has full
1861 precision for the mantissa. It does not support any exceptions.
1862 It is very simple, and approximately 3-6 times faster than NWFPE.
1863
1864 It should be sufficient for most programs. It may be not suitable
1865 for scientific calculations, but you have to check this for yourself.
1866 If you do not feel you need a faster FP emulation you should better
1867 choose NWFPE.

1877 release notes and additional status information.

1879 Say N if your target does not have VFP hardware.

1903 Say Y here to include the kernel code necessary if you want to run
1904 Acorn RISC OS/Arthur binaries under Linux. This code is still very
1905 experimental; if this sounds frightening, say N and sleep in peace.
1906 You can also say M here to compile this support as a module (which
1907 will be called arthur).
