2018-06-15scripts/qemu.py: introduce set_console() methodCleber Rosa
The set_console() method is intended to ease higher level use cases that require a console device. The amount of intelligence is limited on purpose, requiring either the device type explicitly, or the existence of a machine (pattern) definition. Because of the console device type selection criteria (by machine type), users should also be able to define that. It'll then be used for both '-machine' and for the console device type selection. Users of the set_console() method will certainly be interested in accessing the console device, and for that a console_socket property has been added.

2018-06-15exec.c: Handle IOMMUs in address_space_translate_for_iotlb()Peter Maydell
Currently we don't support board configurations that put an IOMMU in the path of the CPU's memory transactions, and instead just assert() if the memory region fonud in address_space_translate_for_iotlb() is an IOMMUMemoryRegion. Remove this limitation by having the function handle IOMMUs. This is mostly straightforward, but we must make sure we have a notifier registered for every IOMMU that a transaction has passed through, so that we can flush the TLB appropriately when any of the IOMMUs change their mappings.

2018-06-15iommu: Add IOMMU index argument to notifier APIsPeter Maydell
Add support for multiple IOMMU indexes to the IOMMU notifier APIs. When initializing a notifier with iommu_notifier_init(), the caller must pass the IOMMU index that it is interested in. When a change happens, the IOMMU implementation must pass memory_region_notify_iommu() the IOMMU index that has changed and that notifiers must be called for. IOMMUs which support only a single index don't need to change. Callers which only really support working with IOMMUs with a single index can use the result of passing MEMTXATTRS_UNSPECIFIED to memory_region_iommu_attrs_to_index().

2018-06-15aspeed_scu: Implement RNG registerJoel Stanley
The ASPEED SoCs contain a single register that returns random data when read. This models that register so that guests can use it. The random number data register has a corresponding control register, however it returns data regardless of the state of the enabled bit, so the model follows this behaviour. When the qcrypto call fails we exit as the guest uses the random number device to feed it's entropy pool, which is used for cryptographic purposes.

2018-06-15exec.c: Don't accidentally sign-extend 4-byte loads in subpage_read()Peter Maydell
In subpage_read() we perform a load of the data into a local buffer which we then access using ldub_p(), lduw_p(), ldl_p() or ldq_p() depending on its size, storing the result into the uint64_t *data. Since ldl_p() returns an 'int', this means that for the 4-byte case we will sign-extend the data, whereas for 1 and 2 byte reads we zero-extend it. This ought not to matter since the caller will likely ignore values in the high bytes of the data, but add a cast so that we're consistent.

2018-06-15bswap: Add new stn_*_p() and ldn_*_p() memory access functionsPeter Maydell
There's a common pattern in QEMU where a function needs to perform a data load or store of an N byte integer in a particular endianness. At the moment this is handled by doing a switch() on the size and calling the appropriate ld*_p or st*_p function for each size. Provide a new family of functions ldn_*_p() and stn_*_p() which take the size as an argument and do the switch() themselves.

2018-06-15hw/core/or-irq: Support more than 16 inputs to an OR gatePeter Maydell
For the IoTKit MPC support, we need to wire together the interrupt outputs of 17 MPCs; this exceeds the current value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which should be enough for anyone). The tricky part is retaining the migration compatibility for existing OR gates; we add a subsection which is only used for larger OR gates, and define it such that we can freely increase MAX_OR_LINES in future (or even move to a dynamically allocated levels[] array without an upper size limit) without breaking compatibility.

2018-06-15arm: Don't crash if user tries to use a Cortex-M CPU without an NVICPeter Maydell
The Cortex-M CPU and its NVIC are two intimately intertwined parts of the same hardware; it is not possible to use one without the other. Unfortunately a lot of our board models don't do any sanity checking on the CPU type the user asks for, so a command line like qemu-system-arm -M versatilepb -cpu cortex-m3 will create an M3 without an NVIC, and coredump immediately. In the other direction, trying a non-M-profile CPU in an M-profile board won't blow up, but doesn't do anything useful either: qemu-system-arm -M lm3s6965evb -cpu arm926 Add some checking in the NVIC and CPU realize functions that the user isn't trying to use an NVIC without an M-profile CPU or an M-profile CPU without an NVIC, so we can produce a helpful error message rather than a core dump.

2018-06-15hw/arm/armv7m: Remove unused armv7m_init() functionPeter Maydell
Remove the now-unused armv7m_init() function. This was a legacy from before we properly QOMified ARMv7M, and it has some flaws: * it combines work that needs to be done by an SoC object (creating and initializing the TYPE_ARMV7M object) with work that needs to be done by the board model (setting the system up to load the ELF file specified with -kernel) * TYPE_ARMV7M creation failure is fatal, but an SoC object wants to arrange to propagate the failure outward * it uses allocate-and-create via qdev_create() whereas the current preferred style for SoC objects is to do creation in-place Board and SoC models can instead do the two jobs this function was doing themselves, in the right places and with whatever their preferred style/error handling is.

2018-06-15stellaris: Stop using armv7m_init()Peter Maydell
The stellaris board is still using the legacy armv7m_init() function, which predates conversion of the ARMv7M into a proper QOM container object. Make the board code directly create the ARMv7M object instead.
