will do.

Yes that's strange. On the other hand, harmony has these gpios, the Toshiba 
source defines them, and they don't hurt. So I vote for keeping them for 
consistency reasons.

It was good that you mentioned these gpios as I found an error in my original
post. On AC100, the external mmc is connected to the first sdhci, not the 
second. Even Toshiba/Compal seem to were confused as they also added a wrong 
comment to the source (which I blindly followed).

I'll send an updated version soon, which also adds PAZ00 to tegra_defconfig.

Thanks!
