--Apple-Mail=_77D43C90-74EB-4D16-B3E4-32CEEC032C28 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=windows-1252 I don't object, but I'm not sure why we need this. I'd rather see a comment in the BEAGLEBONE config indicating that it can be used with beaglebone-black.dts. Generally, I want us to move away from compiled-in DTBs. The BEAGLEBONE config works just fine on either one and it's what I plan to continue using going forward. Part of the boot loader's job is to load the correct DTB. The images built by Crochet today already do this and produce images that boot on either old or new BeagleBone using the BEAGLEBONE config. U-Boot already has logic to detect the board, load the correct DTB, and the same BEAGLEBONE kernel then runs just fine. Here are the U-Boot patches if you'd like to do this as well: = https://github.com/kientzle/crochet-freebsd/tree/master/board/BeagleBone/f= iles (There's also a copy of the compiled U-Boot and associated files at: http://people.freebsd.org/~kientzle/beaglebone-and-black-bootfiles.tgz Moving forward, I'd like to see us generally consolidate ARM kernel configurations. I have some (still very experimental) ideas for combining the RPi and BeagleBone kernels into a single kernel, but with my limited time, that will be a fairly long-term project. If anyone's at BSDCan who would like to talk about it=85. I'll be at the "Beyond BuildWorld" session on Thursday=85. ;-) Yes, this is certainly useful for people net booting the BeagleBone Black for developing kernel drivers, but I'm not sure why we would bother having it checked-in.
