freebsd-dev/sys/mips/conf/AP135.hints
Adrian Chadd 27b3a39a8f 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.
