Author: adrian Date: Sat Oct 10 05:00:18 2015 New Revision: 289106 URL: https://svnweb.freebsd.org/changeset/base/289106 Log: Update the AP135 reference design flash layout to be more useful. * Shuffle the kernel to be at the beginning * Give the kernel 2mb, the rootfs 6mb, and 'mib0' the rest * put the cfg parition just before the ART calibration data for the wifi part in the SoC * .. and make sure ART points to the right 64k region. I've updated the freebsd-wifi-build wiki the instructions on using this. If someone has an AP135 with 8MB SPI flash then this won't work; everything minus the big mib0 partition is just a bit over 8MB. Come see me if this ever happens (you'll likely just have to shrink the rootfs and the kernel a little in order to make it fit.) Tested: * AP135 reference board.
