Page directory and early page tables are allocated using
platform_allocate_region() and they don't need to be identity mapped
since commits 9103470bd and a7c69a4b1.

UART is mapped to kernel virtual address range since commit f5f10a9ec
so it does not overlap with user address range any more.

An effort was started some time ago to consolidate all internal
documentation in the git tree. However, this was just an accumulation of
files in various formats without any strucutre or way to browse it,
which results in no one even knowing that we have docs here.
This converts most of the files to restructuredtext and uses Sphinx to
generate an HTML browsable user manual (with a table of content and a
first attempt to put things in a global hierarchy).
There are almost no changes to the documentation content in this commit
(some obviously obsolete things were removed). The plan is to get the
toolchain up and running to make these docs easily available, and only
then see about improving the content. We can migrate some things off the
wiki and website, and rework the table of contents to have some more
hierarchy levels because currently it's a bit messy.

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* VM files (these are rather outdated) are now in kernel/vm.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.
