* target/microblaze: Use env_cpu, env_archcpuRichard Henderson2019-06-101-3/+2Star
| | | | | | | | | | | | | | Cleanup in the boilerplate that each target must define. Replace mb_env_get_cpu with env_archcpu. The combination CPU(mb_env_get_cpu) should have used ENV_GET_CPU to begin; use env_cpu now. Move cpu_mmu_index below the include of "exec/cpu-all.h", so that the definition of env_archcpu is available.

* Move target-* CPU file into a target/ folderThomas Huth2016-12-201-0/+303
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
