Bug#876773: flash-kernel: Please add support for the original SolidRun CuBox (Dove)
Hi Vagrant,
thanks for your reply!
I have now come up with a revised script taking your comments into
consideration.

Yes. I just wanted to be verbose.

True.
I decided to structure it very similar, but avoid the copy.

That is what I meant.
It would be neat using just console=${console}, but the console variable
in u-boot is set to
console=console=ttyS0,115200useNandHal=single
which is not nice style.
So I hardcoded it now.

Ack.
After regenerating my initrd, I managed to boot with cmdline:
console=ttyS0,115200n8 quiet
