[RFC PATCH 0/6] Port PPC64/PowerNV MMU tests to QEMU

[Leandro Lupori]

Add support to run softmmu tests for ppc64 and ppc64le.
To make it possible, a new "virtual" TCG test target,
ppc64le-softmmu, was created.

Also add the MMU tests from
https://github.com/legoater/pnv-test, that are the Microwatt
tests adapted to use a PowerNV console and to better integrate
with QEMU test infrastructure.

To be able to finish the test and return an exit code to the
calling process, the Processor Attention instruction is used.
As its behavior is implementation dependent, in QEMU PowerNV
it just calls exit with GPR[3] value, truncated to an uint8_t.

Cédric Le Goater (2):
  target/ppc: Add support for the Processor Attention instruction
  ppc/pnv: Activate support for the Processor Attention instruction

Leandro Lupori (4):
  tests/tcg/ppc64: add basic softmmu test support
  tests/tcg: add support for ppc64le softmmu tests
  tests/tcg/ppc64: add MMU test sources
  tests/tcg/ppc64: add rules to build PowerNV tests
