2013-02-01target-unicore32: Rename CPU subtypesAndreas Färber2-3/+7
In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. No functional changes for -cpu arguments.

2013-02-01target-unicore32: Mark as unmigratableAndreas Färber4-26/+9
CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a hw_error(). Therefore we can without problems suppress registration of "cpu_common" VMState by dropping CPU_SAVE_VERSION define and provide an unmigratable "cpu" VMStateDescription for UniCore32CPU at device level instead, where we can attach this the QOM way.

2013-01-28target-unicore32: Use type_register() instead of type_register_static()Andreas Färber1-1/+1
According to its documentation, type_register_static()'s TypeInfo argument should exist for the life type of the type. Therefore use type_register() when registering the list of CPU subtypes. No functional change with the current implementation. Cf. 918fd0839eeafc83bd4984364321a947d29041fe for arm. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-01-27target-unicore32: Detect attempt to instantiate non-CPU type in cpu_init()Andreas Färber2-2/+27
Consolidate model checking into a new uc32_cpu_class_by_name(). If the name matches an existing type, also check whether that type is actually (a sub-type of) TYPE_UNICORE32_CPU. This fixes, e.g., -cpu puv3_dma asserting. Cc: qemu-stable@nongnu.org Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-12-23configure: allow disabling pixman if not neededRobert Schiele1-0/+2
When we build neither any system emulation targets nor the tools there is actually no need for pixman library. In that case do not enforce presence of that library on the system.
