5e077a7767 hw/m68k/mcf5206: Embed m5206_timer_state in m5206_mbar_state
There's no need to explicitely allocate the memory here, we can
simply embed it into the m5206_mbar_state instead.

These are now redundant with the scr2 and old_scr2 fields in NeXTPC. Rename
the function from nextscr2_write() to next_scr2_rtc_update() to better
reflect its purpose. At the same time replace the manual bit manipulation with
the extract32() and deposit32() functions.

22cf5ee30f next-cube.c: move static old_scr2 variable to NeXTPC
Move the old_scr2 variable to NeXTPC so that the old SCR2 register state is
stored along with the current SCR2 state.

Since the SCR2 register is 32-bits wide, convert old_scr2 to uint32_t and
update the SCR2 register access code to allow unaligned writes.

Note that this is a migration break, but as nothing will currently boot then
we do not need to worry about this now.

f2a80c6ede m68k: Instantiate the ESP SCSI controller for the NeXTcube machine
The NeXTcube uses a NCR 53C90 SCSI interface for its disks, so we should
be able to use the ESP controller from QEMU here. The code here has been
basically taken from Bryce Lanham's GSoC 2011 contribution, except for
the next_scsi_init() function which has been rewritte as a replacement
for the esp_init() function (that has been removed quite a while ago).

Note that SCSI is not working yet. The ESP code likely needs some more
fixes first and there still might be some bugs left in they way we wire
it up for the NeXT-Cube machine.

d43e967f69 q800-glue.c: convert to Resettable interface
Convert the GLUE device to 3-phase reset. The legacy method
doesn't do anything that's invalid in the hold phase, so the
conversion is simple and not a behaviour change.

f18a288632 q800: reimplement mac-io region aliasing using IO memory region
The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".

Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.
