Subject: dtc: libfdt: Introduce a can_assume check in fdt_check_full
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=487994d65cf305e943e4fd4efb56283f214f0611;p=thirdparty%2Fu-boot.git

dtc: libfdt: Introduce a can_assume check in fdt_check_full

The current upstream method of having a function omit various tests is
to use the can_assume macro. Take the logic we had previously been using
and instead make it a can_assume(PERFECT) check within fdt_check_full
itself.
