The quote get removed by the Makefile rule so the -D compiler option uses an unquoted string > > > +For this particular issue you can use DEFAULT_DEVICE_TREE instead:: > > Maybe use double tickquotes to highlight this is a variable? i.e. > > ``DEFAULT_DEVICE_TREE`` > > ? Will do. Regards, Simon

See below.
Some boards use a CONFIG option to specify the value of this variable. This is normally handled by efi_get_distro_fdt_name() but in the case of sunxi this does not work, since 'soc' is sunxi, but the files are in the allwinner directory. Provide a work-around for this particular case.
