Could you send the layout of the resulting ptable which you were
able to boot the device with ?
parted device unit s print
it would help me to do the right fixes in kiwi

yes. I talked to Alex about this disk layout and I think it's the
best we can do. You are right the vboot firmware caused this layout
and it is used for the Chromebook in the first place. For this device
we needed a real GPT. With raspberry the layout is also a good idea
but we have to use a sync_mbr ptable type. My plan is to configure
this with:
firmware="vboot" loader="berryboot"
- should create a sync_mbr ptable type
- should create three partitions
1. a fat16 containing u-boot.bin plus config.txt plus cmdline.txt
plus all the raspberry required firmware stuff. as kernel in
config.txt we use u-boot.bin which loads boot.scr from the
second partition
2. ext2 boot partition, with boot.scr kernel and initrd
3. root partition
The kiwi script hooks as we use for setting up the different loaders
for the arm boards can be used to change all that. The common parts
which are clear should be done by kiwi though
Thanks
Regards,
Marcus
