Hello Craig

Hopefully the attachments will be accepted.

The kernel defconfig from beagleboard.org:

1> doesn't set DEPRECATED_PARAM_STRUCT [=y] in the kernel .config. uEnv.txt 
(uboot) passes in the console config as "console=ttyO0,115200n8"

2> doesn't set EXT2_FS [=y] and the default buildroot .config FS image is 
ext2. at least for the beaglebone black and I'm trying to keep things sane.

You'll want to do a make source and them make linux-menuconfig and change 
the parameters above.

I haven't created a patch file because I'm lazy.

Also attached is my patch (hack) for dtc, derived from Robert Nelsons 
bb.org-overlays.

The dtc patch file goes into BR2_GLOBAL_PATCH_DIR , 
BR2_GLOBAL_PATCH_DIR"/dtc"

Look in the buildroot .config for how I set BR2_GLOBAL_PATCH_DIR. you'll 
need to point that to your own global patch directory.

Regards

Chris
