Hi folks,

I'm in the process of tidying up my STM32 SPI driver code for more
general release.  While it all works fine for on-chip memory (my
particular use case), the DMA does not support access to external memory
(generic STM3210E-EVAL).  This means that I'll need to add optional
support for DMA bounce buffering via the on-chip SRAM.

I'm sure that this is a problem which must have been addressed on other
platforms.  Is there a convention for setting up such a DMA-specific
section in the memory layout files - and are there any existing examples
you can point me to?

Chris.
