It's just a different name for the same thing.

Well, if you compare for example against  libressl-portable , then
this git repository has 180 files with more than 20,000 lines.
We are adding a lot of functionality, and anyone who wants to use
this will have to pay the price.  But this is what I mentioned
before:  I think the kernel code has already been tweaked with an
eye on resource consumption, while standard public libraries have
not.

The kernel code may be big, but I would be surprised if there are
smaller and leaner alternatives with similar quality?

As for who is willing to maintain it: I have no idea.  Usually it
turns out to be the original implementoer / who pushed the code
upstream into U-Boot.

Best regards,

Wolfgang Denk
