[U-Boot] s3c2416 usb ohci issue

[Zoltan Gyarmati <mr.zoltan.gyarmati@gmail.com>]

Hi,

i'm trying to bring up the current mainline u-boot version on a
SOM2416II board, which based on the s3c2416 SOC. Already the base
booting had some challenges and required some patching (mostly based on
Jos? Miguel Gon?alves' patchset from September 2012), so now the
booting, the serial console and the ethernet works well, but
unfortunately i got blocked with the OHCI support. I'm using the "new"
general ohci support (ohci-hcd.c), and as the CPU init function i use
the appropriate functions from ohci-s3c24xx.c.
After the u-boot succesfully started, and calling the 'usb start'
command, it recognizes succesfully only the root hub, and when trying to
init the USB storage device, it fails with a DEVICENOTRESPONDING error.
Please find the full boot log here:  http://pastebin.com/APrDJ0GR  , the
config (among with the full tree) here:
https://github.com/Cimitech/uboot/blob/v2013.07-2416/include/configs/mini2416.h

Is there anybody else who was recently trying to make this work? Any
hints which way i should start with the debugging? What i found similar
issues were mostly related to slow, or not proper USB memory sticks, so
i tried with several devices, and also played around with the related
timeouts, without any success.

Thanks for any hints in advance, best regards
