-The STM32H7 series has preliminary support: there is a working REPL via
-USB and UART, as well as very basic peripheral support, but some things do
-not work and none of the advanced features of the STM32H7 are yet supported,
-such as the clock tree.  At this point the STM32H7 should be considered as a
