It is of course always a good idea to use  the  latest  and  greatest
versions  of  the software, but U-Boot is a boot loader, and it has a
clearly defined interface to the kernel  -  and  great  attempts  are
being  made  to  keep  this  interface  unchanged  or, if changes are
necessary, to perform them in a way that stays compatible.

I see no reason why even old versions of U-Boot could cause  problems
with  recent Linux kernels. Actually I have seen very old versions of
U-Boot (like U-Boot-0.3.x) seen in production use with recent  kernel

In your case it was probably a bug that had been fixed,  but  not  an
incompatibility with current kernels.
