Linux kernel 5.4 will introduce a new memory map for SWIM device.
(aee6bff1c325 ("m68k: mac: Revisit floppy disc controller base addresses"))
Until this release all MMIO are mapped between 0x50f00000 and 0x50f40000,
but it appears that for real hardware 0x50f00000 is not the base address:
the MMIO region spans 0x50000000 through 0x60000000, and 0x50040000 through
0x54000000 is repeated images of 0x50000000 to 0x50040000.

If you want to test the machine, it doesn't yet boot a MacROM, but you can
boot a linux kernel from the command line.
You can install your own disk using debian-installer with:
./qemu-system-m68k \
-M q800 \
-serial none -serial mon:stdio \
-m 1000M -drive file=m68k.qcow2,format=qcow2 \
-net nic,model=dp83932,addr=09:00:07:12:34:57 \
-append "console=ttyS0 vga=off" \
-kernel vmlinux-4.15.0-2-m68k \
-initrd initrd.gz \
-drive file=debian-9.0-m68k-NETINST-1.iso \
-drive file=m68k.qcow2,format=qcow2 \
-nographic
If you use a graphic adapter instead of "-nographic", you can use "-g"
to set the size of the display (I use "-g 1600x800x24").

Currently the ptimer design uses a QEMU bottom-half as its
mechanism for calling back into the device model using the
ptimer when the timer has expired. Unfortunately this design
is fatally flawed, because it means that there is a lag
between the ptimer updating its own state and the device
callback function updating device state, and guest accesses
to device registers between the two can return inconsistent
device state.
We want to replace the bottom-half design with one where
the guest device's callback is called either immediately
(when the ptimer triggers by timeout) or when the device
model code closes a transaction-begin/end section (when the
ptimer triggers because the device model changed the
ptimer's count value or other state). As the first step,
rename ptimer_init() to ptimer_init_with_bh(), to free up
the ptimer_init() name for the new API. We can then convert
all the ptimer users away from ptimer_init_with_bh() before
removing it entirely.
(Commit created with
git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/'
and three overlong lines folded by hand.)

Coverity currently complains that the "if (0x00 & (0x80 >> (phase - 8))"
in next-cube.c can never be true. Right it is. The "0x00" is meant as value
of the control register of the RTC, which is currently not implemented yet.
Thus, let's add a register variable for this now. However, the RTC
registers are currently defined as static variables in nextscr2_write(),
which is quite ugly. Thus let's also move the RTC variables to the main
machine state instead. In the long run, we should likely even refactor
the whole RTC code into a separate device in a separate file, but that's
something for calm winter nights later... as a first step, cleaning up
the static variables and shutting up the warning from Coverity should
be sufficient.

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.
Passing a NULL function pointer results in ELF Notes being skipped.
The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

change default and wrong timer behaviour, for example to continuously
trigger periodic timer when load value is equal to "0".

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

[Fix compilation without the spice devel packages. - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.
The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.
As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Printing CPU registers is not helpful during machine initialization.
Moreover, these are straightforward configuration or "can get
resources" errors, so dumping core isn't appropriate either. Replace
hw_error() by error_report(); exit(1). Matches how we report these
errors in other machine initializations.
