[Qemu-devel] [PATCH v3 31/35] microblaze: enable multi-arch |
Date: |
Sat, 18 Jul 2015 02:40:41 -0700 |
Multi-arch conversion consisting of:
* Compiling out all target-microblaze private contents of cpu.h
when doing multi-arch build
* Defining the QOM cpu hooks
* Add microblazeel to multi-support list
Signed-off-by: Peter Crosthwaite <address@hidden>
---
I guess I could split to multi patches but it will bloat this series!
Changed since RFCv2:
Remove macro undefs (obsoleted)
Remove arch prefixing redefinitions of cpu-defs symbols (obsoleted)
Compile out SR_PC in multi-arch
Remove configury changes
Remove arch-obj conversions
