I see both as necessary in an MCU : unless you expect the RTS (or FreeRTOS 
underneath) to provide drivers for every peripheral out there - not just 
basic I2C, CANBUS etc but ADCs and everything under the sun that can be 
integrated onto the same silicon. (Of course the RTS must have exclusive 
access to a subset of these : one timer, one UART for example)

So yes, I was hinting at a BSP. For the RTS itself, your approach does 
have the merit that someone else has probably already done the work, 
albeit in C!

That's the problem...
