* qom: Put name parameter before value / visitor parameterMarkus Armbruster2020-07-101-16/+15Star

| | | | | | | | | | | | | | | | | From 'Application Note AN521', chapter 4.7: The SMM implements four SBCon serial modules: One SBCon module for use by the Color LCD touch interface. One SBCon module to configure the audio controller.

While the object_initialize() function doesn't take an 'Error *errp' argument, the object_initialize_child() does. Since this code is used when a machine is created (and is not yet running), we deliberately choose to use the &error_abort argument instead of ignoring errors if an object creation failed. This choice also matches when using sysbus_init_child_obj(), since its code is: void sysbus_init_child_obj(Object *parent, const char *childname, void *child, size_t childsize, const char *childtype) { object_initialize_child(parent, childname, child, childsize, childtype, &error_abort, NULL); qdev_set_parent_bus(DEVICE(child), sysbus_get_default()); } Suggested-by: Eduardo Habkost <ehabkost@redhat.com> Inspired-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190507163416.24647-16-philmd@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

* hw/arm/iotkit: Rename IoTKit to ARMSSEPeter Maydell2019-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | The Arm IoTKit was effectively the forerunner of a series of subsystems for embedded SoCs, named the SSE-050, SSE-100 and SSE-200: https://developer.arm.com/products/system-design/subsystems These are generally quite similar, though later iterations have extra devices that earlier ones do not. We want to add a model of the SSE-200, which means refactoring the IoTKit code into an abstract base class and subclasses (using the same design that the bcm283x SoC and Aspeed SoC family implementations do). As a first step, rename the IoTKit struct and QOM macros to ARMSSE, which is what we're going to name the base class. We temporarily retain TYPE_IOTKIT to avoid changing the code that instantiates a TYPE_IOTKIT device here and then changing it back again when it is re-introduced as a subclass.

* hw/arm/mps2-tz: Instantiate SPI controllersPeter Maydell2018-08-241-6/+32
| | | | | | | | | | | | | | The SPI controllers in the MPS2 AN505 board are PL022s. We have a model of the PL022, so create these devices. We don't currently model the LCD controller that sits behind one of the PL022s; the others are intended to control devices that sit on the FPGA's general purpose SPI connector or "shield" expansion connectors.

| | | | | | | | | | | | | The AN505 FPGA image includes four PL081 DMA controllers, each of which is gated by a Master Security Controller that allows the guest to prevent a non-secure DMA controller from accessing memory that is used by secure guest code. Create and wire up these devices.

* hw/arm/mps2-tz: Put ethernet controller behind PPCPeter Maydell2018-06-151-9/+23
| | | | | | | | | | | | | | | | | The ethernet controller in the AN505 MPC FPGA image is behind the same AHB Peripheral Protection Controller that handles the graphics and GPIOs. (In the documentation this is clear in the block diagram but the ethernet controller was omitted from the table listing devices connected to the PPC.) The ethernet sits behind AHB PPCEXP0 interface 5. We had incorrectly claimed that this was a "gpio4", but there are only 4 GPIOs in this image. Correct the QEMU model to match the hardware.

* Remove checks on MAX_SERIAL_PORTS that are just bounds checksPeter Maydell2018-04-261-2/+1Star
| | | | | | | | | | | | | Remove checks on MAX_SERIAL_PORTS that were just checking whether they were within bounds for the serial_hds[] array and falling back to NULL if not. This isn't needed with the serial_hd() function, which returns NULL for all indexes beyond what the user set up.

* mps2-an505: New board model: MPS2 with AN505 Cortex-M33 FPGA imagePeter Maydell2018-03-021-0/+503
Define a new board model for the MPS2 with an AN505 FPGA image containing a Cortex-M33. Since the FPGA images for TrustZone cores (AN505, and the similar AN519 for Cortex-M23) have a significantly different layout of devices to the non-TrustZone images, we use a new source file rather than shoehorning them into the existing mps2.c.
