I've made significant progress and would
appreciate any feedback:
github.com/kientzle/freebsd-beaglebone
This has been massively refactored so it can
build system images for a variety of
ARM-based boards. Right now:
* BeagleBone builds and boots cleanly again. ;-)
In particular, I've caught up with some changes to
ubldr in -CURRENT and switched to using the
stable DENX U-Boot sources instead of the
rapidly-evolving (and often broken) TI/Arago sources.
* PandaBoard: I have a completely untested
sketch. Someone with a PandaBoard will need
to work through the U-Boot configuration to make
this work.
* RaspberryPi: I have a completely untested
sketch that will need more work before it can
build a bootable image.
Others? If you're interested in adding support for
other boards, let me know. All the boards above:
* Are ARMv6-based.
* Have a kernel configuration in -CURRENT
* Boot from an MBR-partitioned SD card or USB stick
* Boot using U-Boot and ubldr
It should be pretty straightforward to add support
for other boards that meet these criteria. The hardest
part is working up the correct U-Boot patches; hopefully
the existing BeagleBone patches will prove helpful
to anyone who wants to work on this.
