ok. Take your time. It turns out that the infos I had were a bit
misleading. I've been told the mmc driver was using some gpios and the
gpios are GPIO_1_0/1_1 and GPIO_1_7/1_8... which are in fact the esdhc1
and esdhc2 CD and WP.
This means :
- with proper iomux configuration, WP detection is working fine
- I should still be able to test WP on GPIO
Thanks,
Arnaud
