The four interrupts of the PCI bus are connected to the same UIC pin
on the real Sam460ex. Evidence for this can be found in the UBoot
source for the Sam460ex in the Sam460ex.c file where
PCI_INTERRUPT_LINE is written. Change the ppc440_pcix model to behave
more like this.
This fixes the problem that can be observed when adding further PCI
cards that got their interrupt rotated to other interrupts than PCI
INT A. In particular, the bug was observed with an additional OHCI PCI
card or an ES1370 sound device.

sam460ex_load_device_tree() handles nearly all possible errors by simply
exiting (within helper functions and macros). It handles two early error
cases by returning an error.
There's no particular point to this, so make it handle those directly as
well, removing the need for the caller to handle a failure. As a bonus it
gives us more specific error messages.

The qemu_fdt_*() helper functions already exit with a message instead of
returning errors, so we don't need to check for errors in the caller.

In a couple of places sam460ex_load_device_tree() calls "raw" libfdt
functions which can fail, but doesn't check for error codes. At best,
if these fail the guest will be silently started in a non-standard state,
or it could fail entirely.
Fix this by using the _FDT() helper macro which aborts on a libfdt failure.

into staging
ppc patch queue 2018-07-03
Here's a last minue pull request before today's soft freeze. Ideally
I would have sent this earlier, but I was waiting for a couple of
extra fixes I knew were close. And the freeze crept up on me, like
always.
Most of the changes here are bugfixes in any case. There are some
cleanups as well, which have been in my staging tree for a little
while. There are a couple of truly new features (some extensions to
the sam460ex platform), but these are low risk, since they only affect
a new and not really stabilized machine type anyway.
Higlights are:
* Mac platform improvements from Mark Cave-Ayland
* Sam460ex improvements from BALATON Zoltan et al.
* XICS interrupt handler cleanups from Cédric Le Goater
* TCG improvements for atomic loads and stores from Richard
Henderson
* Assorted other bugfixes

PPC440 SoCs such as the AMCC 460EX have a DMA controller which is used
by AmigaOS on the sam460ex. Implement the parts used by AmigaOS so it
can get further booting on the sam460ex machine.

sam460ex (or at least this emulation) does not support the "ibm,cpm" power
management. As a result, Linux crashes when trying to access it. Remove
its device tree node. Also, if/when we boot the Linux kernel directly,
serial port clock frequencies in the device tree file will be unset, and
serial port initialization will fail. Add valid frequency values to
the serial ports to be able to use it. Also set valid values for the other
clock nodes otherwise set by u-boot.

Add emulation of aCube Sam460ex board based on AMCC 460EX embedded SoC.
This is not a complete implementation yet with a lot of components
