This is a combination of upstream libfdt commits to fix warnings about comparing signed and unsigned integers: ========== scripts/dtc/libfdt/fdt.c: In function ‘fdt_offset_ptr’: scripts/dtc/libfdt/fdt.c:137:18: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if ((absoffset < offset) ... ========== For a detailed description of the fixes, see the dtc repo: https://git.kernel.org/pub/scm/utils/dtc/dtc.git/log/?id=73e0f143b73d808 For this patch the commits between 73e0f143b73d8088 and ca19c3db2bf62000 have been combined and adjusted for the slight differences in U-Boot's libfdt code base.
