*****************************************************************************
*** Next ***
+- NEW: Reworked STM32 SDMMCv1 and SDMMCv2 drivers, better timeout and clock
+ handling, improved speed for aligned buffers.
- NEW: Added a "waend" field to the thread structure in RT for debug
convenience.
- NEW: Added a para-virtualized HAL port for use in sandboxes.
