Get enough of the mmu working to be able to allocate memory.
Unlike on PowerPC, we get both address and size as 64bit values. So
adjust of_region to allow this.
Also unlike the PPC port, we do not drive the hardware directly, instead we
rely on the openboot primitives to manage the translation table. This
allows staying independant of the hardware, which is a good idea at
least for the bootloader (we can do actual hardware things in the
kernel)

I didn't do anything with sparc for a few weeks (you don't want this
machine running when temperatures already are over 30°...), and I wastd
some time finding back some of the useful information, such as commands
to boot and debug, load and execution address of the bootloader program,
etc. So let's keep these in the documentation directory.

* There is now a 'busses' folder, and the extant USB/SDHCI/Bluetooth/etc.
docs now live in it, instead of various other places.
* kernel/ports is now kernel/arch, like it is in src/system.
SPARC documentation is now in there, too.
* VM files (these are rather outdated) are now in kernel/vm.
* SCSI ASC info removed, this is easily available online and
it doesn't seem to be very relevant.
Now vaguely follows the tree structure of "src", with the exception of
directories that described subsystems spanning more than one "kit" or
"server" (e.g. "media", "midi", "bluetooth") -- these have been left as their
own top-level directory within docs/develop.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
and publish it on the website - comments are still welcome, though.

We might want to use it as a basis for the device manager documentation.

- Borrowed the UHCI basic theory of operation from the freebsd handbook
- Started some work on the internals of devices

ready for testing. Also the documentation is far from complete (it's in it's early phases).
Unfortunately I don't have enough experience in hardware programming to prototype
it first, so I'll be testing the things that I design in the document.
