[Qemu-devel] [PATCH v6 00/16] QEMU OpenRISC support

[Jia Liu <proljc@gmail.com>]

This is the OpenCores OpenRISC 1200 support for QEMU.
Full implementation of the system-model and linux-user-model support.

OpenRISC 1200 is a OpenCores open source CPU,
its architecture manual can be found at
http://opencores.org/svnget,or1k?file=/trunk/docs/openrisc_arch.pdf

A OpenRISC Linux kernel contain initramfs for qemu-system-or32 testing
can be found at
https://docs.google.com/file/d/0BxeTrz3x0CBLSjR3Sk5Vd3h1eDA/edit?pli=1

A OpenRISC hello-world program for qemu-or32 testing can be found at
https://docs.google.com/file/d/0BxeTrz3x0CBLN3RSWUFNYktrU2M/edit?pli=1
