* hw/arm: In STM32L4x5 SOC, connect USART devices to EXTIInès Varhol2024-07-111-13/+11
| | | | | | | | | | | | | | | | The USART devices were previously connecting their outbound IRQs directly to the CPU because the EXTI wasn't handling direct lines interrupts. Now the USART connects to the EXTI inbound GPIOs, and the EXTI connects its IRQs to the CPU. The existing QTest for the USART (tests/qtest/stm32l4x5_usart-test.c) checks that USART1_IRQ in the CPU is pending when expected so it confirms that the connection through the EXTI still works.

* hw/arm : Pass STM32L4x5 SYSCFG gpios to STM32L4x5 SoCInès Varhol2024-04-301-2/+4
| | | | | | | | | | | | | | Exposing SYSCFG inputs to the SoC is practical in order to wire the SoC to the optional DM163 display from the board code (GPIOs outputs need to be connected to both SYSCFG inputs and DM163 inputs). STM32L4x5 SYSCFG in-irq interception needed to be changed accordingly.

* hw/arm: Add minimal support for the STM32L4x5 SoCInès Varhol2024-01-091-0/+265
This patch adds a new STM32L4x5 SoC, it is necessary to add support for the B-L475E-IOT01A board. The implementation is derived from the STM32F405 SoC. The implementation contains no peripherals, only memory regions are implemented.
