MCA: delete all remaining traces of microchannel bus support.
Hardware with MCA bus is limited to 386 and 486 class machines that are now 20+ years old and typically with less than 32MB of memory. A quick search on the internet, and you see that even the MCA hobbyist/enthusiast community has lost interest in the early 2000 era and never really even moved ahead from the 2.4 kernels to the 2.6 series. This deletes anything remaining related to CONFIG_MCA from core kernel code and from the x86 architecture. There is no point in carrying this any further into the future. One complication to watch for is inadvertently scooping up stuff relating to machine check, since there is overlap in the TLA name space (e.g. arch/x86/boot/mca.c).

The MCA bus functions provide a generalised interface to find MCA
|
||||
bus cards, to claim them for a driver, and to read and manipulate POS
|
||||
registers without being aware of the motherboard internals or
|
||||
certain deep magic specific to onboard devices.
|
||||
</para>
|
||||
<para>
|
||||
The basic interface to the MCA bus devices is the slot. Each slot
|
||||
is numbered and virtual slot numbers are assigned to the internal
|
||||
devices. Using a pci_dev as other busses do does not really make
|
||||
sense in the MCA context as the MCA bus resources require card
|
||||
specific interpretation.
|
||||
</para>
|
||||
<para>
|
||||
Finally the MCA bus functions provide a parallel set of DMA
|
||||
functions mimicing the ISA bus DMA functions as closely as possible,
|
||||
although also supporting the additional DMA functionality on the
|
||||
MCA bus controllers.
