Falcon mode for TI DM355

Hello TI experts,

I appreciate that all of the TI DM355 support long since (August 2015) landed in the great board scrap yard in the sky or wherever it is git chooses to hide it!

I may have an upcoming project to reduce boot time on a pre-existing custom platform using the DM355 and wondered if anyone had implemented SPL and Falcon mode for it that didn't make it into mainline or whether this is actually possible at all for this device?

Thanks,

Andy.
