New Revision: 286815
URL: https://svnweb.freebsd.org/changeset/base/286815
Log:
Make dtb file configurable via loader(8) variable. ubldr already checks
"fdt_file" and "fdtfile" U-Boot variables. Add one more check for
"fdt_file" loader(8) variable.
loader(8) variable takes precedence over u-boot env one
