73 The Extended Industry Standard Architecture (EISA) bus was
74 developed as an open alternative to the IBM MicroChannel bus.

76 The EISA bus provided some of the features of the IBM MicroChannel
77 bus while maintaining backward compatibility with cards made for
78 the older ISA bus. The EISA bus saw limited use between 1988 and
79 1995 when it was made obsolete by the PCI bus.

1032 interworking branch is replaced with another code sequence at the

1266 Since there are major incompatibilities between the legacy ABI and
1267 EABI, especially with regard to structure member alignment, this
1268 option also changes the kernel syscall calling convention to
1269 disambiguate both ABIs and allow for backward compatibility support
1270 (selected with CONFIG_OABI_COMPAT).
1271
1272 To use this you need GCC version 4.0.0 or later.

1279 This option preserves the old syscall interface along with the
1280 new (ARM EABI) one. It also provides a compatibility layer to
1281 intercept syscalls that have structure arguments which layout
1282 in memory differs between the legacy ABI and the new ARM EABI
1283 (only for non "thumb" binaries). This option adds a tiny
1284 overhead to all syscalls and produces a slightly larger kernel.
1285 If you know you'll be using only pure EABI user space then you
1286 can say N here. If this option is not selected and you attempt
1287 to execute a legacy ABI binary then the result will be
1288 UNPREDICTABLE (in fact it can be predicted that it won't work
1289 at all). If in doubt say Y.

1646 Say Y here to include the FAST floating point emulator in the kernel.
1647 This is an experimental much faster emulator which now also has full
1648 precision for the mantissa. It does not support any exceptions.
1649 It is very simple, and approximately 3-6 times faster than NWFPE.
1650
1651 It should be sufficient for most programs. It may be not suitable
1652 for scientific calculations, but you have to check this for yourself.
1653 If you do not feel you need a faster FP emulation you should better
1654 choose NWFPE.

1660 Say Y to include VFP support code in the kernel. This is needed
1661 if your hardware includes a VFP unit.
1662
1663 Please see <file:Documentation/arm/VFP/release-notes.txt> for
1664 release notes and additional status information.
1665
1666 Say N if your target does not have VFP hardware.

1690 Say Y here to include the kernel code necessary if you want to run
1691 Acorn RISC OS/Arthur binaries under Linux. This code is still very
1692 experimental; if this sounds frightening, say N and sleep in peace.
1693 You can also say M here to compile this support as a module (which
1694 will be called arthur).
