All remaining changes from the PPC branch. Not well tested yet. Many things are indeed still stubs or WIP code.

- Kernel's entry point is called KiSystemStartup, not NtProcessStartup (now it's done correctly). svn path=/trunk/; revision=32450 2008-02-22 13:41:37 +00:00			`KiSystemStartup:`

t's a bit embarrasing that some of this was undone until recently, but we now correctly communicate the boot-time memory map to kernel land. In question is still how the ppcmmu idea of free pages and the ntoskrnl one will coincide. Lots of things were adapted in ofwldr as ntoskrnl and freeldr changed a bit since this was forked. Also, some hacks were in here to allow ofwldr to be ignorant of how some things were mapped. That's fixed. Many stupid and obvious bugs have been fixed. I've basically gutted a lot of HAL stuff, so it isn't committed here. I had mistakenly used the same array size as x86 did in the ports array in kdcom. This is corrected. I added in some support for boot time device detection (sadly, I haven't yet decided what will become of openfirmware properties yet). Much has been done to simplify the mess that mboot became. svn path=/trunk/; revision=31625 2008-01-06 14:52:00 +00:00			`ori 30,0,0x3030`
