Subject: libfdt: Add fdt16_to_cpu utility function
X-Git-Url: http://git.jdl.com/gitweb/?p=dtc.git;a=commitdiff_plain;h=2cd4c8d27d6b5ea83723754da4eba5d51aa71b95
libfdt: Add fdt16_to_cpu utility function
This utility routine will be used in the variable size cell literal
append code. It is a straightforward adaptation of the fdt32_to_cpu
function.
