2020-10-27hw/misc/bcm2835_cprman: add the DSI0HSCK multiplexerLuc Michel
This simple mux sits between the PLL channels and the DSI0E and DSI0P clock muxes. This mux selects between PLLA-DSI0 and PLLD-DSI0 channel and outputs the selected signal to source number 4 of DSI0E/P clock muxes. It is controlled by the cm_dsi0hsck register.

2020-10-27hw/misc/bcm2835_cprman: add a clock mux skeleton implementationLuc Michel
The clock multiplexers are the last clock stage in the CPRMAN. Each mux outputs one clock signal that goes out of the CPRMAN to the SoC peripherals. Each mux has at most 10 sources. The sources 0 to 3 are common to all muxes. They are: 0. ground (no clock signal) 1. the main oscillator (xosc) 2. "test debug 0" clock 3. "test debug 1" clock Test debug 0 and 1 are actual clock muxes that can be used as sources to other muxes (for debug purpose). Sources 4 to 9 are mux specific and can be unpopulated (grounded). Those sources are fed by the PLL channels outputs. One corner case exists for DSI0E and DSI0P muxes. They have their source number 4 connected to an intermediate multiplexer that can select between PLLA-DSI0 and PLLD-DSI0 channel. This multiplexer is called DSI0HSCK and is not a clock mux as such. It is really a simple mux from the hardware point of view (see https://elinux.org/The_Undocumented_Pi). This mux is not implemented in this commit. Note that there is some muxes for which sources are unknown (because of a lack of documentation). For those cases all the sources are connected to ground in this implementation. Each clock mux output is exported by the CPRMAN at the qdev level, adding the suffix '-out' to the mux name to form the output clock name. (E.g. the 'uart' mux sees its output exported as 'uart-out' at the CPRMAN level.)

2020-10-27hw/misc/bcm2835_cprman: add a PLL channel skeleton implementationLuc Michel
PLLs are composed of multiple channels. Each channel outputs one clock signal. They are modeled as one device taking the PLL generated clock as input, and outputting a new clock. A channel shares the CM register with its parent PLL, and has its own A2W_CTRL register. A write to the CM register will trigger an update of the PLL and all its channels, while a write to an A2W_CTRL channel register will update the required channel only.

2020-10-27hw/misc/bcm2835_cprman: implement PLLs behaviourLuc Michel
The CPRMAN PLLs generate a clock based on a prescaler, a multiplier and a divider. The prescaler doubles the parent (xosc) frequency, then the multiplier/divider are applied. The multiplier has an integer and a fractional part. This commit also implements the CPRMAN CM_LOCK register. This register reports which PLL is currently locked. We consider a PLL has being locked as soon as it is enabled (on real hardware, there is a delay after turning a PLL on, for it to stabilize).

2020-10-27hw/misc/bcm2835_cprman: add a PLL skeleton implementationLuc Michel
There are 5 PLLs in the CPRMAN, namely PLL A, C, D, H and B. All of them take the xosc clock as input and produce a new clock. This commit adds a skeleton implementation for the PLLs as sub-devices of the CPRMAN. The PLLs are instantiated and connected internally to the main oscillator. Each PLL has 6 registers : CM, A2W_CTRL, A2W_ANA[0,1,2,3], A2W_FRAC. A write to any of them triggers a call to the (not yet implemented) pll_update function. If the main oscillator changes frequency, an update is also triggered.

The BCM2835 CPRMAN is the clock manager of the SoC. It is composed of a main oscillator, and several sub-components (PLLs, multiplexers, ...) to generate the BCM2835 clock tree.

2020-10-27hw/gpio: Add GPIO model for Nuvoton NPCM7xxHavard Skinnemoen
The NPCM7xx chips have multiple GPIO controllers that are mostly identical except for some minor differences like the reset values of some registers. Each controller controls up to 32 pins. Each individual pin is modeled as a pair of unnamed GPIOs -- one for emitting the actual pin state, and one for driving the pin externally. Like the nRF51 GPIO controller, a gpio level may be negative, which means the pin is not driven, or floating.

Testing notes: * With -device usb-kbd, qemu will automatically insert a full-speed hub, and the keyboard becomes controlled by the OHCI controller. * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly attached to the port without any hubs, and the device becomes controlled by the EHCI controller since it's high speed capable. * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the keyboard is directly attached to the port, but it only advertises itself as full-speed capable, so it becomes controlled by the OHCI controller. In all cases, the keyboard device enumerates correctly.

2020-10-26migration: Drop unused VMSTATE_FLOAT64 supportPeter Maydell
Commit ef96e3ae9698d6 in January 2019 removed the last user of the VMSTATE_FLOAT64* macros. These were used by targets which defined their floating point register file as an array of 'float64'. We used to try to maintain a stricter distinction between 'float64' (a type for holding an integer representing an IEEE float) and 'uint64_t', including having a debug option for 'float64' being a struct and supposedly mandatory macros for converting between float64 and uint64_t. We no longer think that's a usefully strong distinction to draw and we allow ourselves to freely assume that float64 really is just a 64-bit integer type, so for new targets we would simply recommend use of the uint64_t type for a floating point register file. The float64 type remains as a useful way of documenting in the type signature of helper functions and the like that they expect to receive an IEEE float from the TCG generated code rather than an arbitrary integer. Since the VMSTATE_FLOAT64* macros have no remaining users and we don't recommend new code uses them, delete them.

2020-10-26fuzz: Add fuzzer callbacks to DMA-read functionsAlexander Bulekov
We should be careful to not call any functions besides fuzz_dma_read_cb. Without --enable-fuzzing, fuzz_dma_read_cb is an empty inlined function.

2020-10-26fuzz: Declare DMA Read callback functionAlexander Bulekov
This patch declares the fuzz_dma_read_cb function and uses the preprocessor and linker(weak symbols) to handle these cases: When we build softmmu/all with --enable-fuzzing, there should be no strong symbol defined for fuzz_dma_read_cb, and we link against a weak stub function. When we build softmmu/fuzz with --enable-fuzzing, we link against the strong symbol in generic_fuzz.c When we build softmmu/all without --enable-fuzzing, fuzz_dma_read_cb is an empty, inlined function. As long as we don't call any other functions when building the arguments, there should be no overhead.

2020-10-26fuzz: Add DMA support to the generic-fuzzerAlexander Bulekov
When a virtual-device tries to access some buffer in memory over DMA, we add call-backs into the fuzzer(next commit). The fuzzer checks verifies that the DMA request maps to a physical RAM address and fills the memory with fuzzer-provided data. The patterns that we use to fill this memory are specified using add_dma_pattern and clear_dma_patterns operations.

2020-10-22hw/riscv: Load the kernel after the firmwareAlistair Francis
Instead of loading the kernel at a hardcoded start address, let's load the kernel at the next aligned address after the end of the firmware. This should have no impact for current users of OpenSBI, but will allow loading a noMMU kernel at the start of memory.

Instead of returning the unused entry address from riscv_load_firmware() instead return the end address. Also return the end address from riscv_find_and_load_firmware(). This tells the caller if a firmware was loaded and how big it is. This can be used to determine the load address of the next image (usually the kernel).
