[PATCH v7 01/10] hw/qdev-properties-system: Introduce EndianMode QAPI enum

[Philippe Mathieu-Daudé]

Introduce the EndianMode type and the DEFINE_PROP_ENDIAN() macros.
Endianness can be BIG, LITTLE or unspecified (default).

[PATCH v7 02/10] hw/intc/xilinx_intc: Make device endianness configurable

[Philippe Mathieu-Daudé]

Replace the DEVICE_NATIVE_ENDIAN MemoryRegionOps by a pair
of DEVICE_LITTLE_ENDIAN / DEVICE_BIG_ENDIAN.
Add the "little-endian" property to select the device
endianness, defaulting to little endian.
Set the proper endianness for each machine using the device.

[PATCH v7 03/10] hw/net/xilinx_ethlite: Make device endianness configurable

[Philippe Mathieu-Daudé]

Replace the DEVICE_NATIVE_ENDIAN MemoryRegionOps by a pair
of DEVICE_LITTLE_ENDIAN / DEVICE_BIG_ENDIAN.
Add the "little-endian" property to select the device
endianness, defaulting to little endian.
Set the proper endianness on the single machine using the
device.

[PATCH v7 04/10] hw/timer/xilinx_timer: Make device endianness configurable

[Philippe Mathieu-Daudé]

Replace the DEVICE_NATIVE_ENDIAN MemoryRegionOps by a pair
of DEVICE_LITTLE_ENDIAN / DEVICE_BIG_ENDIAN.
Add the "little-endian" property to select the device
endianness, defaulting to little endian.
Set the proper endianness for each machine using the device.

[PATCH v7 07/10] tests/functional: Explicit endianness of microblaze assets

[Philippe Mathieu-Daudé]

The archive used in test_microblaze_s3adsp1800.py (testing a
big-endian target) contains a big-endian kernel. Rename using
the _BE suffix.

Similarly, the archive in test_microblazeel_s3adsp1800 (testing
a little-endian target) contains a little-endian kernel. Rename
using _LE suffix.

These changes will help when adding cross-endian kernel tests.

Grr, please read:

   Add the "endianness" property to select the device endianness.
   This property is unspecified by default, and machines need to
   make it explicit.

(same in following patches).

Do we still need a TARGET_BIG_ENDIAN ?: check here, too? ... the 
petalogix_ml605_machine_init() code still contains it, though big endian is 
marked as deprecated and untested ...

Anyway, assuming that nobody uses this in big endian anymore:

Same question as in the second patch: Do we still need to take care of 
TARGET_BIG_ENDIAN here?

Not sure this sentence is worth its keep.  It's consistent with existing
