From f4891c398e599f18bbf41eb33885930431f5e1c8 Mon Sep 17 00:00:00 2001 From: Matt Weber Date: Mon, 1 May 2017 23:01:17 -0500 Subject: [PATCH] uboot-tools: disable libfdt swig wrapper The current tools build assumes the host system when trying to detect if swig/python are present. It then uses those tools from the path. The upstream RFC included this commit set's patch but offered up discussion on how to cleanly introduce a better method for detecting swig and using the tools. The tools build really needs to be sysroot and prefix/host dir tools aware.
