The OpenBIOS IDE driver calls udelay() in order to wait for IDE transfers

The high memory virtual memory reservation introduced in r1114 was a mistake.
We need to leave this area as available for clients but simply not allocate
from it so that the 0xffc00000 area is free for kadb on older versions of
SunOS. Since this part is already handled by the introduction of OFMEM_VIRT_TOP
in the same commit then the behaviour is already correct. As reported by Artyom
Tarasenko.

Further tests show that the Sun ESCC serial driver routines are also used for

When binding C functions to Forth words using NODE_METHODs for the SPARC ESCC
serial driver, the C instance parameter pointer was set to be a pointer to a
phys_addr_t.
This is incorrect in the case where sizeof(phys_addr_t) != sizeof(cell) such
as on SPARC32, as the address allocated from the Forth machine would be aligned
to sizeof(cell); hence an alignment exception could be generated on random
occasions on SPARC32 when the allocated address generated by Forth when opening
the device was aligned to just 4 bytes (and not also 8 bytes) when dereferencing
the instance parameter pointer.

If open-dev is called on a raw block device such as cdrom, the current code
will always attempt to interpose a partition handler for the first valid
partition table type it finds.
This is incorrect when opening a raw block device directly as it means we
"fall into" the first valid partition that can be found, rather than using
the full raw device. Fix this by only attempting to interpose a partition
handler if the package arguments are not empty.
This fixes the NetBSD SPARC64 bootloader as reported by
Martin Husemann in https://bugs.launchpad.net/qemu/+bug/1169856.

Similar to the earlier commit for "mmu", do the same for /chosen "memory"
property. Hence all architectures that want the "pretty" memory properties
can provide suitable ihandles if required, and those that don't will not
fail with a NULL pointer dereference from a zero ihandle.
While we're here, correct the SPARC32 initialiser to point to the correct
/virtual-memory node for "mmu" so that once again we can get "pretty"
memory properties on SPARC32.

freelist.
The existing code would incorrectly allow freelist memory to be reused if the
requested size were 0x1000 greater than the freelist item size, rather than the
freelist item size being 0x1000 greater than the requested size.
Since internal memory allocations could be smaller than requested, it would be
possible for a caller to clobber over the internal memory heap causing a crash or
internal memory corruption.

Instead of using the automatic allocator to determine the location of the
Forth dictionary, allocate it at a fixed location just underneath the ROM
itself at 0xffd00000.
This patch also prevents corruption within the RAM of the Forth machine
by ensuring that we allocate virtual memory outside of OpenBIOS itself,
plus reduces the size of the Forth dictionary to 128K so that it meets
the memory constraints required to boot Linux and also kadb from older
versions of SunOS (as reported by Artyom Tarasenko).

One of the primary reasons that issues with the quik bootloader were not
detected earlier was because arch/ppc/qemu/main.c has a separate code path
for forcing an old-world boot when -boot c is passed to QEMU.
This commit implements the bootcode loader as a core OpenBIOS loader which
enables old-world payloads such as quik to be executed using:
load hd:,%BOOT
go
Note that we also fix a bug in mac-parts.c to ensure that we don't try and
interpose a filesystem package when %BOOT is passed as a filename.
