Linux on PPC64 knows only so many chipsets. One of the is the U3. So
we can use that when we're emulating a PPC64 machine, making Linux happy.

There is a draft spec that defines how interrupts are supposed to be mapped
from one bus to another, down to the PIC and CPU interrupt line.
So far we don't implement that spec. But PPC64 Linux requires us to for PCI
devices. So let's create a map here.

When running on Qemu (TCG) time goes by at a constant frequency which
accidently happens to match with Linux's fallback value.
As soon as we go to KVM, the time base suddenly starts going as fast as
the host CPU's time base. So we need to make sure Linux knows about
it, so it can do its timekeeping properly.

This patch implements the following Forth words:
debug <xt> - Mark word for debugging
debug-off - Unmark all words for debugging
resume - Return from subordinate Forth interpreter
The source debugger also implements the following commands when it has
been activated:
Up - Unmark current word for debugging, mark parent and continue
Down - Mark next word for debugging
Trace - Continue execution until end of word displaying
debug information
Rstack - Display contents of the Rstack
Forth - Launch subordinate Forth interpreter

Wrong encoding of "#address-cells" property can lead to a failure
fetching correct value in my-#acells method. According to docs
properties must be encoded with "encode-int". I spent some time
looking at the docs and it is clear that encode-int produces
quad-sized result (of size /l bytes).
This patch fixes pci helpers to encode to 32bit instead of 64bit values,
and correctes my-address and my-unit methods to read 32bit data
to match encode-int rules
modules/bindings.c: also fixed set_int_property and get_int_property
to match encode-int rules

While booting a 64bit kernel, there is a small timeframe where OF and the kernel communicate with each other. Within that timeframe, DSI/ISI interrupts may occur, because some memory is not mapped yet.
Right now in case that happens, we jump into the DSI/ISI interrupt handler which clobbers the high 32 bits of the kernel's registers. In order to circumvent that, let's save/restore all 64 bits of all kernel registers when we get a DSI/ISI interrupt.
This patch enables a PPC64 Linux kernel to boot up to the point where it tries to set up the SLB entries (slbmte), which is not yet implemented in qemu.
v2 implements handling for the HIOR register, bringing interrupt handlers to RAM.

It gets up to the boot prompt and works rather good so far, though I haven't been able to run a kernel yet.
For more recent PowerPC CPUs the PTE layout has changed, so we need to take that into account and create PTEs according to the new layout and at the new physical positions.
