There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

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.

This option prevents any floating-point instructions from being

The 68060 generally uses copyback caching of recently accessed data.

Copyback caching means that memory writes will be held in an on-chip

caching. Writethrough caching means that data is written to memory

Writethrough caching is less efficient, but is needed for some
