From 211cfa503f6cf850ccbd79b1082f9234b603e635 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 1 Sep 2020 05:13:56 -0600 Subject: libfdt: Detected out-of-space with fdt_finish() At present the Python sequential-write interface can produce an error when it calls fdt_finish(), since this needs to add a terminating tag to the end of the struct section. Fix this by automatically expanding the buffer if needed.
