We can't use the return value of load_uimage() for the kernel because it
can't account for BSS size, and the PowerPC kernel does not relocate
blobs before zeroing BSS.
Instead, we now load at the fixed addresses chosen by u-boot (the normal
firmware for the board).

The PowerPC 4xx SDRAM controller emulation unregisters RAM in its reset
callback. However, qemu_system_reset() is now called at initialization
time, so all RAM is unregistered before starting the guest (!).

The message "Truncating memory to %d MiB to fit SDRAM controller limits"
should be displayed only when a user chooses an amount of RAM which
can't be represented by the PPC 4xx SDRAM controller (e.g. 129MB, which
would only be valid if the controller supports a bank size of 1MB).

We must be able to use a non-native strip executable, but not all
versions of 'install' support the --strip-program option (e.g.
OpenBSD). Accordingly, we can't use 'install -s', and we must run strip
separately.

On KVM for PPC we need to tell the guest which instructions to use when
doing a hypercall. The clean way to do this is to go through an ioctl
from userspace and passing it on to the guest using the device tree.
So let's do the qemu part here: read out the hypercall and pass it on
to the guest's fw_cfg so openBIOS can read it out and expose it again.

Old versions of the BOCHs VGA BIOS (cira 2003) made use of VBE
registers at 0xff80/81. In VBE API version 0xb0c2 these were
moved to 0x1ce/cf. Unfortunately, QEMU still registers handlers
for the old range. If a guest attempts to assign an I/O device
overlapping this region, QEMU exits with a hw_error. Windows
guests seem to like to assign I/O devices to the high end of
the address space, so it's pretty easy to hot add an rtl8139
to a Win2k8 guest and trigger the bug. I can't find any reason
to register these handlers, so let's remove the cruft.

I have a guest OS which sends the command 0xfd to the keyboard
controller during initialization. To get rid of the message
"qemu: unsupported keyboard cmd=0x%02x\n" I added support for
the pulse output bit commands.
I found the following explanation here:
http://www.win.tue.nl/~aeb/linux/kbd/scancodes-11.html#ss11.3
Command 0xf0-0xff: Pulse output bit
Bits 3-0 of the output port P2 of the keyboard controller may
be pulsed low for approximately 6 µseconds. Bits 3-0 of this
command specify the output port bits to be pulsed. 0: Bit should
be pulsed. 1: Bit should not be modified. The only useful version
of this command is Command 0xfe.
(For MCA, replace 3-0 by 1-0 in the above.)
Command 0xfe: System reset
Pulse bit 0 of the output port P2 of the keyboard controller.
This will reset the CPU.

QEMUFileBuffered stops writing when the underlying QEMUFile is not ready,
and tells its producer so. However, when the underlying QEMUFile becomes
ready, it neglects to pass that information along, resulting in stoppage
of all data until the next tick (a tenths of a second).
Usually this doesn't matter, because most QEMUFiles used with QEMUFileBuffered
are almost always ready, but in the case of exec: migration this is not true,
due to the small pipe buffers used to connect to the target process. The
result is very slow migration.
Fix by detecting the readiness notification and propagating it. The detection
is a little ugly since QEMUFile overloads put_buffer() to send it, but that's
the suject for a different patch.

According to scc_escc_um.pdf:
- Reset Highest IUS must update irq status to allow processing
of the next priority interrupt.
- rx interrupt has always higher priority than tx on same channel
The documentation only explicitly says that Reset Highest IUS
command (0x38) clears IUS bits, not that it clears the corresponding
interrupt too, so don't clear interrupts on this command.

configure adds the macro WIN32_LEAN_AND_MEAN to
QEMU_CFLAGS, and SDL_syswm.h defines it, too.
This results in a compiler warning (redefinition of
WIN32_LEAN_AND_MEAN in SDL_syswm.h. That warning prevents
compilations for win32 with warning = error).
Fix this by removing the definition of WIN32_LEAN_AND_MEAN
before including SDL_syswm.h.
