Somebody in the thread at some point said:
| Hi Andy,
|
| Are there any plans to add native ext4 support to Qi? I wanted to move
my root
| partition to ext4 and see if that makes any real difference.

The ext2 parser in Qi came out of U-Boot, it also works for ext3.
Whether it'll also do ext4 I don't know, but it might.

ext4 is becoming "real" now so support would be good, let us know what
you find.

| So far I've done the usual stuff - small ext3 partition with kernel
and append-
| GTA02 (which points to second partition with root). It works ok, but
I'm just
| wondering if having two root= on a command line won't mess up anything
in the
| future (Qi adds first root=).
|> root=/dev/mmcblk0p1 rootdelay=1 root=/dev/mmcblk0p2

A better way to come at that is use the noboot-GTA02 thing

http://wiki.openmoko.org/wiki/Qi#Files

on your normal partition to force it skipped by Qi.  Then it will create
the correct root= on the second one automatically.
