Benjamin Herrenschmidt c5f5f50738 hello_world: Use new headers and frequency from syscon
This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.

Paul Mackerras cf4dfeca36 Change the default cross compiler prefix to powerpc64le-linux-gnu-
That is what is used by the packaged cross-compilers on (at least)
Fedora and Ubuntu.

Paul Mackerras 10f4be4309 tests: Add a test for privileged instruction interrupts
This adds a test that tries to execute various privileged instructions
with MSR[PR] = 1.  This also incidentally tests some of the MSR bit
manipulations.

Michael Neuling 0076f8bf1d XICS test case
Checks interrupt masking and priorities.

Adds to `make test_xics` which is run in `make check` also.

Paul Mackerras 0a95e4bfdd tests: Put an attn instruction at 0x700
This puts an attn instruction at offset 0x700 in each of the tests
so that the test will terminate if a program interrupt is taken.
This means that we can implement the tw instruction to cause a
program interrupt.

Paul Mackerras c13c73f1ae tests: Adjust header inclusions and Makefile.test
This fixes the decrementer, illegal and sc tests to compile
successfully with cross-compilers that don't provide unistd.h
or string.h.  Instead of those headers we include stddef.h.

This also fixes tests/Makefile.test to do what one expects
when CROSS_COMPILE is defined in the environment.

Michael Neuling 9d7df2d507 Add test cases for new exceptions and supervisor state
This adds test cases for:
- sc, illegals and decrementer exceptions
- decrementer overflow
- rfid
- mt/mf sprg0/1 srr0/1
- mtdec
- mtmsrd
- sc

It also adds these test cases to make check/check_light

Anton Blanchard 467630573c Dump CTR, LR and CR on sim termination, and update our tests
Right now our test cases fold the SPRs into the GPRs. That makes
debugging fails more difficult than it needs to be, so print
out the CTR, LR and CR.

We still need to print the XER, but that is in two spots in microwatt
and will take some more work.

This also adds many instructions to the tests that we have added
lately including overflow instructions, CR logicals and mt/mfxer.
