UEFI config is stored in NOR flash. When writing a new board recovery
image, the user will generally not want to use old and incompatible UEFI
config.
By placing a blank image where the UEFI config resides, the first time
the user flashes a new recovery image, the config will be erased.
Subsequent reboots will not change the timestamp of blank.img, so the
NOR will remain intact for the user to keep persistent UEFI config over
reboots.

Instead of renaming the kernel in the filesystem to norkern, leave it as
Image and set the name stored in NOR as "norkern".

images.txt allows files to be saved into NOR flash with a different name
from the filename.
So for the DTB files, I rename juno.dtb or juno-r1.dtb in NOR flash as
board.dtb.
This means that the UEFI config for both Juno R0 and R1 can be the same.

Some users were having problems fitting larger kernels into our NOR
Flash layout.
The larger kernel was overlapping with the .dtb files, so I have moved
them up in NOR Flash to make more space for the kernel.

Adding a dummy uInitrd ramdisk to NOR flash images.
The dummy ramdisk image can be passed to the kernel for systems that
don't boot using a ramdisk, but are booting using a bootloader that is
configured to expect a ramdisk by default.
