Now I’m wondering if I have the wrong version of meta-freescale. The 
recipes-kernel/linux directory contains the following files:

linux-qoriq_4.19.bb
linux-imx_4.9.123.bb
linux-fslc-lts-4.19.bb
linux-fslc-imx_4.9-1.0.x.bb
linux-qoriq_4.14.bb
linux-imx-headers_4.9.123.bb
linux-fslc-imx-rt_4.1-2.0.x.bb
linux-fslc_5.0.bb
linux-imx-mfgtool_4.9.123.bb

I guess I could use linux-imx_4.9.123 to get me a bit further forward or 
bbappend linux-fslc-imx_4.9-1.0.x.bb and pull the latest SRVREV out of 
git://github.com/Freescale/linux-fslc.git

The default 4.9.67 boots and I have run the initial tests on it 
successfully.  I was looking to update it to something that would be a 
better long term option if this test exercise turns into a full product 
development.

Having built the 4.19.66 kernel with the changed KERNEL_DEVICETREE 
setting I now have a compile issue with the Vivante drivers which 
appears to come from some DMA related functions having moved header file 
somewhere along the way.
