Dear Akashi Takahiro,

Who: usually the responsible custodians
"Custodians" don't always mean sub-system maintainers. Right?
It's just a different name for the same thing.
In fact, I have already imported relevant kernel code into U-Boot and it now works perfectly with my experimental UEFI secure boot patch, but see the total size (and numbers) of files imported is quite big. I wonder who is willing to maintain them:
...
37 files changed, 6409 insertions(+), 11 deletions(-)
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
