Add a new misc test suite with addpcis tests The two tests obtain NIA with bl+mflr+addi and then compare it against addpcis with the minimum and maximum immediate operand values. They were also tested on a real POWER9 system (in userspace) for good measure. Signed-off-by: Shawn Anastasio <shawn@anastas.io>
Test 01:PASS
Test 02:PASS
tests: Add tests for the PVR The PVR is a privileged read-only SPR. Test reading and writing in both supervisor and problem state. In supervisor state reading returns microwatt's assigned PVR number and writing is a noop. In problem state both reading and writing cause privileged instruction interrupts.

Test 03:PASS
Test 04:PASS
tests/misc: Add a test for correct CTR and LR updating by branches This adds a test with a bdnzl followed immediately by a bdnz, to check that CTR and LR both get evaluated and written back correctly in this situation. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
Test 05:PASS
