RIOT supports two distinct families of the MSP430: The [MSP430 x1xx]
MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible
MCU families the code was located in the msp430fxyz folder, resulting
in case of the UART driver in particularly bizarre code looking roughly
like this:
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
This splits the peripheral drivers for USCI and USART serial IP blocks
into separate files and relocates everything in cpu/msp430, similar to
how cpu/stm32 is organized.
