DMA module

There are two types of DMA module exists in STM32 chips: old-style (STM32F1XX-style) and new-style.

Here table of DMA modules:

Family	DMA-style
STM32F1XX	old-style
STM32F2XX	new-style
STM32F4XX	new-style
STM32L0XX	old-style
STM32L1XX	old-style

DMA module supported through dma.h module. Actually dma.h module just checks selected chip and includes appropriate module. There are 2 modules:

• stm32_dma_f1xx.h
• stm32_dma_f4xx.h

First module (stm32_dma_f1xx.h) implements support for old-style DMA module.

Second module (stm32_dma_f4xx.h) implements new-style DMA module.
