a struct device * corresponding to the ISA bus device. The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.
These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

Chris Demetriou. Filecore and MBR handling has been split out into
separate files. Still needs some work before this could become MI.
Also fix the way in which arm32 filecore checksums are calculated so
that sectors filled with the same byte will not pass the checksum.
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used. If they are not, a message will be displayed on
the console.
Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed. These changes will aid debugging
of broken device drivers.

While strict alignment is not strictly necessary on the x86, ensuring
proper alignment can aid performance, and help make drivers more portable
to architectures (like the Alpha and StrongARM) which _do_ require strict
alignment.
