[Qemu-devel] [PATCH v3 01/15] target-tricore: Add target stubs and qom-c

From: Bastian Koppelmann
Subject: [Qemu-devel] [PATCH v3 01/15] target-tricore: Add target stubs and qom-cpu
Date: Mon, 4 Aug 2014 18:38:38 +0100 
Add TriCore target stubs, and QOM cpu.

Signed-off-by: Bastian Koppelmann <address@hidden>
---
v2 -> v3:
    - Add cache for PSW_USB bits and psw_write/_read functions.
    - Add tricore_feature, set_feature functions and enum of cpu features.
    - Remove translate_init.c.
    - Move init code from translate_init.c to cpu.c and use type_register 
instead of a custom list.
    - Add cpu model aurix and tc1796, which use set_feature.
    - Move tricore_cpu_list to helper.c and now uses GSList.
    - Move cpu_tricore_init from translate.c to helper.c and now uses 
cpu_generic_init (see patch v3[04/15])
