Hi all,

I realized that we have a bug in libfdt. This got fixes by upstream commit [1]: aa7254d ("libfdt: return correct value if #size-cells property is not present")

which was added to the Linux kernel with commit: c2e7075ca830 ("scripts/dtc: Update to upstream version v1.4.7-57-gf267e674d145")

Now my question is, how shall I integrate this fix into u-boot. Shall I just apply the necessary commits: aa7254d libfdt: return correct value if #size-cells property is not present c12b2b0 libfdt: fdt_address_cells() and fdt_size_cells()

Yes

Or shall I sync the whole libfdt as done in the Linux kernel? In that case, to which version shall I update, just to v1.4.7-57-gf267e674d145 or to the actual Linux kernel version v1.5.0-30-g702c1b6c0e73?

This is not possible as libfdt has increased its code size in a release release. I have sent a series to fix that but it still needs work.
