| Interesting, so SDHC is working properly? Does it see all the card? I'm

| the s3c24xx.

I can't give an exhaustive answer but it definitely both assesses the
size of the SHDC correctly and mounts p2 fine, which is right down the
far end of the card (p1 being the main bulk of the card space).

We have used SDHC on 2442 fine both with Qi (our U-Boot doesn't get
various things right and can't touch past 4GB) and Linux.

Can't disagree with you there, but on GTA02 the story was that you can't
change the uSD without pulling the battery, so it didn't matter.  On
GTA03 the rootfs is on there.  So live swapping out uSD is not
realistic, we can say it is likely static media for the session, so it's
a fairly legit way to say card detect is not meaningful.
