2018-05-28	stm32: Add support for STM32F0 MCUs.	Damien George

2018-05-04	stm32/dma: Fix duplicate typedef of struct, it's typedef'd in dma.h.	Damien George

2018-05-02	stm32/irq: Define IRQ priorities directly as encoded hardware values.	Damien George
	For a given IRQn (eg UART) there's no need to carry around both a PRI and SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART). Instead, the IRQ_PRI_UART value has been changed in this patch to be the encoded hardware value, using NVIC_EncodePriority. This way the NVIC_SetPriority function can be used directly, instead of going through HAL_NVIC_SetPriority which must do extra processing to encode the PRI+SUBPRI. For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants remain unchanged in their value. This patch also "fixes" the use of raise_irq_pri() which should be passed the encoded value (but as mentioned above the unencoded value is the same as the encoded value for priority grouping 4, so there was no bug from this error).
2018-05-02	stm32/dma: Always deinit/reinit DMA channels on L4 MCUs.	Peter D. Gray
	The problem is the existing code which tries to optimise the reinitialisation of the DMA breaks the abstraction of the HAL. For the STM32L4 the HAL's DMA setup code maintains two private vars (ChannelIndex, DmaBaseAddress) and updates a hardware register (CCR). In HAL_DMA_Init(), the CCR is updated to set the direction of the DMA. This is a problem because, when using the SD Card interface, the same DMA channel is used in both directions, so the direction bit in the CCR must follow that. A quick and effective fix for the L4 is to simply call HAL_DMA_DeInit() and HAL_DMA_Init() every time.
2018-04-10	stm32/dac: Add support for H7 MCUs.	iabdalkader
	Includes a fix for H7 DAC DMA requests.
2018-03-28	stm32/dma: Remove H7 SDMMC DMA descriptors.	iabdalkader
	The H7 SD peripheral has direct connection to MDMA instead.
2018-03-17	stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.	Damien George
	The CMSIS files for the STM32 range provide macros to distinguish between the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc. Prefer to use these instead of custom ones.
2018-03-09	stm32/dma: Add DMA support for H7 MCUs.	iabdalkader

2018-02-13	stm32: Update HAL macro and constant names to use newer versions.	Damien George
	Newer versions of the HAL use names which are cleaner and more self-consistent amongst the HAL itself. This patch switches to use those names in most places so it is easier to update the HAL in the future.
2017-09-06	ports: Make new ports/ sub-directory and move all ports there.	Damien George
	This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.
