Comment(by andy):
Yes bootloader has already been rewritten into Qi and rejects everything
that wastes time in U-Boot. There's possibly another 500ms that can come
out of it by playing some difficult tricks but that is it now since it
only spends like 3-4s there in total.
I don't think the kernel boot phase can lose much more either, it gets
into INIT in a few more seconds. For Qi -> SD Card boot on GTA02 now it's
11s from pressing power button to Ash prompt.
We need to start packaging Qi (Mickey wrote a bb file for it already) into
the repos and making sure that the kernel package is compatible (Qi needs
the kernel file in /boot/uImage-GTA02.bin rather than just
/boot/uImage.bin to allow for multiple kernels in the same rootfs). But I
realize with recent events it didn't just get any easier to get things
packaged :-((
