Hi Andy,

The above error is from u-boot and is indicating that you don't have 
enough free space in your fdt blob to add the /chosen node and properties.

The best solution is to use the "-S" and "-R" parameters to dtc to 
create a blob with enough extra space in it to hold the necessary 
information.
