Thank you for the patch! I'll test its buildability and sponsor it.
At some point it would be nice to evaluate the big accumulated delta in
Ubuntu's flash-kernel and rebase on Debian's

Title:
Raspberry Pi 3 support
Status in flash-kernel package in Ubuntu:
In Progress
Bug description:
Note that this makes a few assumptions:
1) Will not work as-is (but is safe to apply); updated u-boot (Debian:
#823524) and linux-firmware-raspi2 (LP: #1578745) will also be
required to take advantage of booting on the RPi3. Details at
https://wiki.ubuntu.com/ARM/RaspberryPi/RaspberryPi3
2) For some reason, u-boot mkenvimage creates a uboot.env using the
RPi2 config which u-boot HEAD just doesn't read, citing a CRC error.
This occurs even when using mkenvimage from HEAD. I'm still trying to
determine if it's a bug with u-boot, but boot.scr works fine. I've
translated the uboot.env to its equivalent boot.scr script and it
works fine, so I don't see why we can't just use boot.scr on the RPi3.
(saveenv within the u-boot shell writes a uboot.env which it can
subsequently re-read, interestingly.)
3) The all.db entry, minus the move to boot.scr, is based on the RPi2
entry above, right down to the "XXX".
