drivers/flash: stm32: Add qspi-nor flash-controller Add support for DMA based STM32 QSPI NOR flash controller. Driver configures both NOR flash and also QSPI hardware block. Reuses existing jesd216 library. QSPI hardware block handling is done through the use of Cube HAL API. This requires the use of HAL interface also for DMA besides zephyr DMA driver. Zephyr DMA driver is used only for IRQ routing while HAL driver handles the IP block. To achieve this it is required to: -Configure both Cube and Zephyr drivers at init. -Inform Zephyr driver that current channel handling will be done by another instance and only a limited configuration should be done. For this last part, a unused parameter is overridden in order to transmit the information.

kconfig: fix dt_node_has_prop and add nodelabel functions The Kconfig function "dt_node_has_prop" was using label as its parameter, where other functions use either chosen or path. The documentation says that the parameter is path, so this patch makes the function as documentation says and as other functions in the file. The additional nodelabel functions were added as counterparts that are using nodes labels instead of paths. Signed-off-by: Michał Barnaś <mb@semihalf.com>

kconfig: stm32: Select CONFIG_USE_STM32_HAL_MDMA when QSPI is used The stm32 HAL code for qspi (SHA1: 5c8275071ec1cf160bfe8c18bbd93): stm32cube/stm32h7xx/drivers/src/stm32h7xx_hal_qspi.c implicitly depends on the stm32h7xx_hal_mdma.c driver as it uses unconditionally 'HAL_MDMA_Abort_IT()' function. To avoid build breaks - no matter if QSPI IP block works with DMA or interrupts - the CONFIG_USE_STM32_HAL_MDMA shall be defined. Signed-off-by: Lukasz Majewski <lukma@denx.de>
