Problems creating new openwrt for dir-862l, spi and ath10k problems

Is there any way to debug why spi-nor driver is not loading? (and causing kernel panic because root can't be found). the m25p80 driver loads but is having problems reading the squashfs (instead thinking its an empty jffs2

this is on v19 for supporting new device dir-862

the snapshot git works for the spi (using spi-nor) but the ath10k does not load. error 135 or 145 i think.

thanks for any clues.
