files to vendor-provided ones. It should make easier to adopt platform code to new revisions of hardware and to use DTS overlays for various Beaglebone extensions (shields/capes). Original dts filenames were not changed, they're now wrappers over dts files provided by TI. So make sure you update .dtb files on your devices as part of kernel update GPIO addressing was changed: instead of one global /dev/gpioc0 there are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25 on /dev/gpioc3 On Pandaboard serial console devices was changed from /dev/ttyu0 to /dev/ttyu2 so you'll have to update /etc/ttys to get login prompt on serial port in multiuser mode. Single user mode serial console should work as-is Differential Revision: https://reviews.freebsd.org/D2146 Reviewed by: rpaulo, ian, Michal Meloun, Svatopluk Kraus
