e4f7001d9c stm32/sdcard: Use only a single DMA stream for both SDIO TX/RX. 
No need to be wasteful on DMA resources.

b0c8a94b41 stm32/dma: Pass DMA direction as parameter to dma_init not in cfg struct 
Some DMA channels (eg for SDIO) can be used in both directions and this
patch allows such peripherals to dynamically select the DMA direction.

47550ef2cd stm32: For MCUs that have PLLSAI allow to set SYSCLK at 2MHz increments. 
MCUs that have a PLLSAI can use it to generate a 48MHz clock for USB, SDIO
and RNG peripherals.  In such cases the SYSCLK is not restricted to values
that allow the system PLL to generate 48MHz, but can be any frequency.
This patch allows such configurability for F7 MCUs, allowing the SYSCLK to
be set in 2MHz increments via machine.freq().  PLLSAI will only be enabled
if needed, and consumes about 1mA extra.  This fine grained control of
frequency is useful to get accurate SPI baudrates, for example.

670a2a3396 stm32/Makefile: Allow external BOARD_DIR directory to be specified. 
This makes it easy to add a custom board definition outside of the
micropython tree, keeping the micropython submodule clean and official.

Initial Grand Central definition 
It has a ton of pins in a Mega form-factor

This also includes a change to init the stack earlier. It fixes
a crash that occurs if the flash doesn't start correctly and the
original spot isn't reached.

Introduce displayio to render graphics to displays. 
It's designed to minimize RAM footprint by using Sprites to
represent objects on the screen. The object model also facilitates
partial screen updating which reduces the bandwidth needed to display.

This is all handled in C. Python simply manipulates the objects with
the ability to synchronize to frame timing.
