I checked the source, it's result from s3c2410_ts_connect() in
s3c2410_ts.c. Even the GPIO configuration (GPGCON) is correct in uboot.
TS module would modify these important bits. 

But doesn't these bits affect resume logic for GTA01?
This caution is not mentioned in S3C2410 datasheet. 
That is, GPG[13:15] are not functional pins in NAND boot mode in 2410.

So I think this patch should be applied on GTA02 if TS module is
