[Qemu-devel] [PATCH v1 00/30] target-sparc: add niagara OpenSPARC T1 sun4v emulation

[Artyom Tarasenko]

This patch series adds a Niagara OpenSPARC T1 sun4v machine.
The most important new feature: it can boot Solaris 10 / sparc64.
The machine uses a firmware released by Sun as a part of the OpenSPARC project.

The series are available under:
https://github.com/artyom-tarasenko/qemu/tree/sun4v-v1

The command line for booting Solaris 10 / sparc:

sparc64-softmmu/qemu-system-sparc64 -M niagara -L /path/to/S10image/ -nographic 
-m 256 -drive if=pflash,readonly=on,file=/path/to/S10image/disk.s10hw2

Changes to v0:
Rebased on top of current master
Use lowercase machine name (Mark)
Fixed build on i686
Fixed user-mode build (Richard)
Fixed per review comments from Richard
Added Reviewed-by to the unmodified patches reviewed in the previous round
