Boot failures in -next due to 'ARM: dts: imx: Remove skeleton.dtsi'

[Guenter Roeck]

Hi,

my 'sabrelite' and 'imx25-pdk' qemu boot tests are failing in linux-next.

Bisect for the sabrelite failure points to commit 'ARM: dts: imx: Remove skeleton.dtsi'.

Bisect log is attached. Complete test logs are at
http://kerneltests.org/builders/qemu-arm-next/builds/571/steps/qemubuildcommand/logs/stdio

Boot log for imx25-pdk:

qemu-system-arm: findnode_nofail Couldn't find node /chosen: FDT_ERR_NOTFOUND

Boot log for sabrelite:

Build is imx_v6_v7_defconfig and multi_v7_defconfig with imx6dl-sabrelite.dtb,
and imx_v4_v5_defconfig with imx25-pdk.dtb.

Any idea what might be wrong ?

Thanks,
Guenter
