* arm: Remove system_clock_scale globalPeter Maydell2021-09-011-2/+0Star
| | | | | | | | | | All the devices that used to use system_clock_scale have now been converted to use Clock inputs instead, so the global is no longer needed; remove it and all the code that sets it.

* hw/arm/stm32f405: Wire up sysclk and refclkPeter Maydell2021-09-011-5/+7
| | | | | | | | | | | | | | | | | | | | | Wire up the sysclk and refclk for the stm32f405 SoC. This SoC always runs the systick refclk at 1/8 the frequency of the main CPU clock, so the board code only needs to provide a single sysclk clock. Because there is only one board using this SoC, we convert the SoC and the board together, rather than splitting it into "add clock to SoC; connect clock in board; add error check in SoC code that clock is wired up". When the systick device starts honouring its clock inputs, this will fix an emulation inaccuracy in the netduinoplus2 board where the systick reference clock was running at 1MHz rather than 21MHz.

* hw/arm: Display CPU type in machine descriptionPhilippe Mathieu-Daudé2021-02-031-1/+1
| | | | | | | | | | | | | Most of ARM machines display their CPU when QEMU list the available machines (-M help). Some machines do not. Fix to unify the help output.

* hw/arm/netduino2, netduinoplus2: Set system_clock_scalePeter Maydell2020-08-031-0/+10
| | | | | | | | | | | | | | | | The netduino2 and netduinoplus2 boards forgot to set the system_clock_scale global, which meant that if guest code used the systick timer in "use the processor clock" mode it would hang because time never advances. Set the global to match the documented CPU clock speed of these boards. Judging by the data sheet this is slightly simplistic because the SoC allows configuration of the SYSCLK source and frequency via the RCC (reset and clock control) module, but we don't model that.
