[U-Boot] Passing information from SPL to next stage

[Chris Packham]

Hi,

Is there a standard way of passing information discovered by the SPL
onto the next boot stage?

I'm guessing for platforms that support the new driver model it's
possible to add/update information in the device-tree, but what about
platforms that don't currently use the new driver model.

I had a quick search of the mailing list and docs but didn't find
anything obvious. If I've missed something feel free to point me at
it.

Thanks,
Chris
