Subject: tools: ifdtool: Do not write region while its size is negative
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=6c4247e98eb3b1bf7ec19b61915c803db5670ad0;p=u-boot.git

tools: ifdtool: Do not write region while its size is negative

We should ignore those regions whose size is negative. These are
typically optional and unused regions (like GbE and platform data).
