v2:
Patch 1:
- Added "32-bit" wording to commit message
- Added 'unlikely' specifier to hreg_compute_hflags_value conditional
- Added PPE42_ prefix to ISR definitions
- Moved ISR_MCS* definitions from excp_helper.c to cpu.h
- Moved common target/ppc/cpu_init.c code to a common function
- Added 'likely' specifier to gen_mtmsr conditional
- Formatting changes to fit comments within 80 character limit
Patch 3:
- Added hw/ppc/ppe42_machine.c to MAINTAINERS (myself as maintainer)
Patch 4:
- Added tests/functional/test_ppc_ppe42.py to MAINTAINERS file
This patchset adds support for the IBM PPE42 processor,
including a simple machine providing a platform for
testing the PPE42 instructions.
The PPE42 processor is used as an embedded processor in
the IBM Power9, Power10 and Power12 processors for various
tasks. It is basically a stripped down version of the
IBM PowerPC 405 processor, with some added instructions
for handling 64-bit loads and stores and some 64-bit
logical operations.
For more information on the PPE 42 processor please visit:

A functional test is included. This test downloads a
prebuilt test image from:
https://github.com/milesg-github/ppe42-tests
Building the image rquires a forked version of an old
version of GCC, which can be found here:

Thanks,
