Ouch, I've never seen so few explanations when it comes to add a new ABI...

Can you explain why this is needed at all ? How can it be usefull for an application for example ? Why make it a device ?

I mean there are plenty of SoC supports in the kernel (take a look to arch/arm) and none of them need that so far.

So at least we can expect some motivations to include this stuff in mailine.

Bye.
