That is a warning that you are just installing the new u-boot on the
SD card to NAND. It comes only on the first boot with this SD card.

So it is a feature of the bootloader and not to blaim any version of
QtMoko for.

The latest recommendation is to have a separate SD card to flash
new boot loaders (since this should be needed quite rarely).

And another SD or several for working/experimenting with different
systems. But it is still possible to live/work with a single one (if big
enough for everything).

It was not possible to make the bootloader flash itself into NAND
and still show the standard boot splash image. This is because the
OMAP BootROM remembers that it did boot on power up from SD.
So U-Boot from SD can't reboot to u-boot from NAND. And if it can't
we can't implement the "flash only once" feature properly.

This probably also reflashes the old bootloader but does not show the red screen.
