+CC Simon, I'm worried this might blow the size of all SPLs , which is not the thing we'd like to see.

It might need a bit of work - here's a buildman run:

Just what I was worried about.
So there are some code size changes (which may not be a big deal at 15 -60 bytes) but it breaks lots of powerpc boards.
Can we instead add CONFIG_SPL_OF_LIBFDT?
What would be the difference between having CONFIG_OF_LIBFDT enabled in SPL (which is the case now) and having CONFIG_SPL_OF_LIBFDT enabled ? The naming seems a bit difficult to comprehend to me.
Sorry for late reply as fully tight up with something.
To minimize the impact, we can create fdtdec_get_uint32 in lib/fdtdec_common.c. Then we can drop this patch. Any thought?
Sounds good. Or you could use fdtdec_get_int().
