If someone has time for it, the I2C and SPI drivers should be rewritten 
to use the new frameworks.

https://docs.rtems.org/branches/master/bsp-howto/i2c.html

https://docs.rtems.org/branches/master/bsp-howto/spi.html

These frameworks provide the Linux user-space APIs.

The RPI support in FreeBSD is quite good, so it shouldn't be a big issue 
to integrate it in libbsd.

Yes, BSP documentation is a big issue. We have to find a common place 
for it and make sure the documentation and the source code are in sync.
