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  :-((
