From 67f49b98671a4b4bd20bc78f3bb049a8e7ffcf22 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 17 Mar 2017 16:14:33 -0600 Subject: Adjust libfdt.h to work with swig There are a few places where libfdt.h cannot be used as is with swig: - macros like fdt_totalsize() have to be defined as C declarations - fdt_offset_ptr() and fdt_getprop_namelen() need special treatment due to a TODO in the wrapper for fdt_getprop(). However they are not useful to Python so can be removed Add #ifdefs to work around these problem.
