I understand your concern. First OLB stands for Other Logic Block which
does not say much about it!

It is used to expose SoC specific configuration such as for example
reset, clock or pinctrl. We have a few series nearly ready to be send to
add support for them, each of them will use this block. So declaring
this block since the beginning avoid to have dependencies between these
series and they will only depend of this current initial series.

Is it OK for you ?

Besides fixing the typo I can add the following explanation to the
commit log: "It is used to expose SoC specific configuration such as for
example reset, clock or pinctrl"
