Add TriCore target stubs, and QOM cpu, and Maintainer
Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>
---
v6 -> v7:
- TRICORECPU -> TriCoreCPU.
- TRICORECPUClass -> TriCoreCPUClass.
- CPUTRICOREState -> CPUTriCoreState.
- TRICORECPUInfo: Add terminator.
- TRICORECPUInfo -> TriCoreCPUInfo.
- Remove ARM-style IRQ and FIQ lines.
- CPUTRICOREState: target_ulong -> uint32_t.
- CPUTRICOREState: Move mask defines below the struct.

...the text you've actually used is LGPL 2+, not GPL2+. That's
fine if that's what you wanted, but I thought I'd check given the

yep, LGPL 2+ is fine for me. Thanks for check :).

It would be good if you could fix this in your next round of tricore
