Hopefully that was enough time for people to enjoy their summer
vacations and welcome new additions to the family.

Please work with sboyd to add the board-id to the dtbTool. We don't put
board-ids in the dts file. We post-process the dtb file and add them then.
sboyd has all the info he needs for this, I believe its just with legal
now. Will remove for V2.
It would be nice if we could get this dtbTool to automagically run as
part of the build system.

Please use reserved-memory{}. And why are they setting aside 4k at the
beginning? Trying to cover up corruption issues?
I only have the existing kernel (3.10) and no insight as to why this is
needed. Something very interesting and/or unexpected was that I needed
memreserve when using earlycon combined with
CONFIG_DEBUG_DRIVER && CONFIG_DEBUG_DEVRES
in order for the target / phone to boot. It have very well booted its
just I cant tell given the serial debug is the way I currently have to
gain visibility into the status of the phone.
But when I turned off the a fore mentioned config options and continued
to use earlycon it booted fine.
Removing memreserve.

Please add whatever config options you have to the default defconfig. we don't
define board specific configs for ARM64 platforms. Or I should say, they won't
be accepted into the kernel.
Also, please separate defconfig changes into separate patches.
Will keep the changes to the absolute minimum.
Looks like I am going to need these 3
+CONFIG_BLK_DEV_RAM=y
+CONFIG_BLK_DEV_RAM_COUNT=y
+CONFIG_BLK_DEV_RAM_SIZE=16384
as this unit doent have all the bits'N pieces working currently and is
_ONLY_ able to boot a ramdisk.
