- - implement flash driver
-   - see arch/arm/src/stm32/stm32_flash.c and related
-     - both banks could be mapped with care taken not to erase the active code.
-       - perhaps the MPU could block code corruption?
-
-   - once implemented, the free() cmd replacement can show flash information.

- - Seen crashes when running serial ports below 921600
-
-    - COM34 (UART1, ttyS1) runs the smoothest with 'serialblaster' test...
-    the other two (UART0, USART1) seem to stutter...
-
-   - created a cpuhog test. Each instance takes a semaphore, burns cpu for 6ms and then releases
-     the sem to exercises semaphores passing and a busy cpu. The first two instances become a
-     producer/consumer pair using a pipe (FIFO) to exercise the fileio data passing.
-       -> no crashes with 8 instances running. (No MMU, No BASEPRI)
-       -> no crashes with 8 instances running. (MMU + BASEPRI)
-          -> not however that the serial ports are very finicky with BASEPRI enabled!
-            This setup sends single charactes for each produced or consumed block,
-            and doesn't seem to have any issues:

- - USB serial not quite stable when pushing lots of data
-
- - UARTs don't use DMA. We may need this for high baudrates.
-   - Inbound hardware flow control requires dma.
