[ptxdist] boot problem w/ barebox

["Enrico Weigelt, metux IT consult" <enrico.weigelt@gr13.net>]

Hi folks,


I've got a really strange booting problem on an phycore-imx6
based board (pretty much the same as mira):

* barebox v2017.06.1-phy2 comes up properly, but cant boot
   the kernel (v4.13) - just hangs w/o any output (not even
   uncompression message)
* putting the kernel manually into the factory-image (sdcard)
   w/ old 2015 barebox boots the kernel
* w/ DEBUG_LL + earlyprintk it doesn't even does that, just
   hangs like w/ new barebox


Here's the last output I've got: (added few more debug outputs)

 > Loading ARM Linux zImage '/mnt/mmc/boot/zImage'
 > Loading devicetree from '/mnt/mmc/boot/imx6q-phytec-mira-rdk-emmc.dtb'

My first suspicion was zero'ed DT memory node (which OTOH doesn't
explain why earlyprintk doesn't work), but fixing that didn't help.

Could there be any vital low-level init missing in the new bbx ?
Maybe the entry point correct ?

Any ideas where I could have a deeper look at ?


thx.
