2023-11-20hw/arm/stm32f100: Report error when incorrect CPU is usedPhilippe Mathieu-Daudé1-4/+0
The 'stm32vldiscovery' machine ignores the CPU type requested by the command line. This might confuse users, since the following will create a machine with a Cortex-M3 CPU: $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1 Set the MachineClass::valid_cpu_types field (introduced in commit c9cf636d48 "machine: Add a valid_cpu_types property"). Remove the now unused MachineClass::default_cpu_type field. We now get: $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1 qemu-system-aarch64: Invalid CPU type: neoverse-n1-arm-cpu The valid types are: cortex-m3-arm-cpu Since the SoC family can only use Cortex-M3 CPUs, hard-code the CPU type name at the SoC level, removing the QOM property entirely.

2021-09-01hw/arm/stm32f100: Wire up sysclk and refclkPeter Maydell1-0/+4
Wire up the sysclk and refclk for the stm32f100 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 stm32vldiscovery board where the systick reference clock was running at 1MHz rather than 3MHz.

2021-09-01hw/arm: Don't allocate separate MemoryRegions in stm32 SoC realizePeter Maydell1-0/+4
In the realize methods of the stm32f100 and stm32f205 SoC objects, we call g_new() to create new MemoryRegion objects for the sram, flash, and flash_alias. This is unnecessary (and leaves open the possibility of leaking the allocations if we exit from realize with an error). Make these MemoryRegions member fields of the device state struct instead, as stm32f405 already does.

2021-07-09stm32f100: Add the stm32f100 SoCAlexandre Iooss1-0/+57
This SoC is similar to stm32f205 SoC. This will be used by the STM32VLDISCOVERY to create a machine.
