2014-01-08arm/xilinx_zynq: Always instantiate the GEMsPeter Crosthwaite
Don't conditionalise GEM instantiation on networking attachments. The device should always be present even if not attached to a network. This allows for probing of the device by expectant guests (such as OS's). This is needed because sysbus (or AXI in Xilinx's real hw case) is not self identifying so the guest has no dynamic way of detecting device absence. Also allows for testing of the GEM in loopback mode with -net none.

2014-01-08char/cadence_uart: Remove TX timer & add TX FIFO statePeter Crosthwaite
This tx timer implementation is flawed. Despite the controller attempting to time the guest visable assertion of the TX-empty status bit (and corresponding interrupt) the controller is still transmitting characters instantaneously. There is also no sense of multiple character delay. The only side effect of this timer is assertion of tx-empty status. So just remove the timer completely and hold tx-empty as permanently asserted (its reset status). This matches the actual behaviour of instantaneous transmission. While we are VMSD version bumping, add the tx_fifo as device state to prepare for upcomming TxFIFO flow control. Implement the interrupt generation logic for the TxFIFO occupancy.

2013-12-24hw: cannot_instantiate_with_device_add_yet due to pointer propsMarkus Armbruster
Pointer properties can be set only by code, not by device_add. A device with a pointer property can work with device_add only when the property may remain null. This is the case for property "interrupt_vector" of device "etraxfs,pic". Add a comment there. Set cannot_instantiate_with_device_add_yet for the other devices with pointer properties, with a comment explaining why. Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer property must not remain null" blatantly obvious in the OMAP devices. Only device "smbus-eeprom" is actually changed. The others are all sysbus devices, which get cannot_instantiate_with_device_add_yet set in their abstract base's class init function. Setting it again in their class init function is technically redundant, but serves as insurance for when sysbus devices become available with device_add, and as documentation.

2013-12-23pci-host: Consistently set cannot_instantiate_with_device_add_yetMarkus Armbruster
Many PCI host bridges consist of a sysbus device and a PCI device. You need both for the thing to work. Arguably, these bridges should be modelled as a single, composite devices instead of pairs of seemingly independent devices you can only use together, but we're not there, yet. Since the sysbus part can't be instantiated with device_add, yet, permitting it with the PCI part is useless. We shouldn't offer useless options to the user, so let's set cannot_instantiate_with_device_add_yet for them. It's already set for Bonito, Grackle, i440FX and Raven. Document why.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-12-20roms: Flush icache when writing roms to guest memoryAlexander Graf
We use the rom infrastructure to write firmware and/or initial kernel blobs into guest address space. So we're basically emulating the cache off phase on very early system bootup. That phase is usually responsible for clearing the instruction cache for anything it writes into cachable memory, to ensure that after reboot we don't happen to execute stale bits from the instruction cache. So we need to invalidate the icache every time we write a rom into guest address space. We do not need to do this for every DMA since the guest expects it has to flush the icache manually in that case. This fixes random reboot issues on e5500 (booke ppc) for me.

2013-12-20spapr-rtas: add ibm, (get|set)-system-parameterAlexey Kardashevskiy
This adds very basic handlers for ibm,get-system-parameter and ibm,set-system-parameter RTAS calls. The only parameter handled at the moment is "platform-processor-diagnostics-run-mode" which is always disabled and does not support changing. This is expected to make "ppc64_cpu --run-mode=1" happy.
