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.

2020-10-27hw/arm/raspi: add a skeleton implementation of the CPRMANLuc Michel
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. This commit adds a skeleton of the CPRMAN, with a dummy register read/write implementation. It embeds the main oscillator (xosc) from which all the clocks will be derived.

Some devices expose GPIO lines. Add a GPIO qdev input to our LED device, so we can connect a GPIO output using qdev_connect_gpio_out(). When used with GPIOs, the intensity can only be either minium or maximum. This depends of the polarity of the GPIO (which can be inverted). Declare the GpioPolarity type to model the polarity.

2020-09-01aspeed/sdmc: Perform memory trainingJoel Stanley
This allows qemu to run the "normal" power on reset boot path through u-boot, where the DDR is trained. An enhancement would be to have the SCU bit stick across qemu reboots, but be unset on initial boot. Proper modelling would be to discard all writes to the phy setting regs at offset 0x100 - 0x400 and to model the phy status regs at offset 0x400. The status regs model would only need to account for offets 0x00, 0x50, 0x68 and 0x7c.

2020-06-26mac_via: rework ADB state machine to be compatible with both MacOS and LinuxMark Cave-Ayland
The existing ADB state machine is designed to work with Linux which has a different interpretation of the state machine detailed in "Guide to the Macintosh Family Hardware". In particular the current Linux implementation includes an extra change to IDLE state when switching the VIA between send and receive modes which does not occur in MacOS, and omitting this transition causes the current mac_via ADB state machine to fail. Rework the ADB state machine accordingly so that it can enumerate and autopoll the ADB under both Linux and MacOS, including the addition of the new adb_autopoll_block() and adb_autopoll_unblock() functions.
