I have done some work on a custom platform based on the PXA255 cpu.
The existing support in the tree was more than enough to get me going,
only had to write drivers for some of the internal peripherals found
on the PXA255 (MMC, SPI, I2C etc.). This was relatively easy because
the hardware was fully documented and I could flash a new bootloader
(u-boot) that played nicely with FreeBSD.
