Most of the GPIO stuff that you'd expect has been finished. Pin control,
I2C, and SPI all work. SPI could use some extra work however, but if you
play around with it enough it'll go. I've been having all sorts of "fun"
getting it working and seriously need to put together some documentation
on what could be considered strange behavior and how to get it working
in the first place since that isn't well documented. I don't think
hardware PWM works unfortunately (not that I've tried). The boot SD card
isn't mountable either. Can see it and read it, but mounting as part of
the file system doesn't work. I've been meaning to take a crack at that
but don't have the time.
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.
