Maybe there is a better way to not hardcode this?  But at least with
the build of lk that I have, the fdt table is at 0x81e00000.  I guess
there must be a more robust way to do this, since presumably lk when
booting the linux kernel directly somehow passes the fdt address.

Subject: [PATCH 02/23] HACK: disable emmc

Hitting some timeout which makes boot take much longer.  And
uefi/boot/rootfs partitions will be on sd-card or usb disk, etc,
so we can just ignore emmc.

Subject: [PATCH 07/23] db410c: use fdt passed from lk

lk patches the fdt to set some device's MAC addresses and more
importantly to patch in the simple-framebuffer node that we want u-boot
to see.

Subject: [PATCH 08/23] db410c: add reserved-memory node to dts

If lk lights up display and populates simple-framebuffer node, it will
also setup a reserved-memory node (needed by simplefb on linux).  But
it isn't clever enough to cope when the reserved-memory node is not
present.
