/sys/devices/system/soc/
/sys/devices/system/soc/unique_id<- Unified way to export an ID for all machs

Arbitrary number of bits? Some will have a 64-bit ID, some will have 32-bit
etc.

Should we say it's a hex string of 64 bits?

Could we provide hooks for the platform that takes the buffer and length
and let the platform do the snprintf()? ?Our devices have a 128-bit
serial number and I'm sure there must be others.

Isn't it better to just make it 64-bit so that apps can always parse it,
and then you can have your high-res numbers under mach?

If there is no solid ABI for this there is no point to make it
generic under /soc/unique_id at all.

/soc/name is another useful thing to have I think.

Apart from this we are now en route to the same color of
bikeshed discussion this patchset saw earlier, Maxime please
just implement something that works for you/us so others
can patch in whatever they need on top later.

Yours,
Linus Walleij
