The m68k port
#############

The Motorola 68000 is an old CPU and not a reasonable target for Haiku. However, later models
which are equipped with a memory management unit could work (slowly).

There is work in progress to target Atari, Amiga, and NeXT hardware platforms.

Todo list
=========

- optimization: remove M68KPagingStructures[*]::UpdateAllPageDirs() and just allocate all the kernel page root entries at boot and be done with it. It's not very big anyway.
- possibly other optimizations in the VM code due to not supporting SMP?

Target platforms information
============================

Generate developer docs with Sphinx 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.
