I'm doing this for the chinese sunXi chipsets (Olimex, Orange-Pi,
Banana-Pi, ...), elbe allows you to copy files to your root filesystem
and use that file in scripts (see the <archive> stanza in the elbe xml
description). I'm using this to copy my boot.scr file to /boot and set
up the bootloader: For the sunXi chipsets the bootloader needs to be at
a certain location inside the boot-sector of an SD-Card image. I'm using
'dd' during the build process to put it there.

What you need to do for your chipset for a successful boot may differ a
lot (e.g. if you don't have an SD image but need to use a NAND flash or
similar).

Sounds like a plan.
