Hello,
I try to get u-boot working with sdhc cards on gta01. I applied patch from Alex
[1]
but it don't work for my sdhc card.
Digging s3c2410 documents, I get it working with a new patch (attached) to
apply on
top Alex's patchs, against u-boot origin/stable.
If you wan't to test it, I published my version of u-boot here :
http://www.starox.org/pub/openmoko/u-boot/
A user already reports me that it won't work with his card, you're
warned ;)
