Other i.MX have its own initialization file. So #if defined(CONFIG_MX31) || defined(CONFIG_MX25) is always true. However, where is this code ? In current u-boot I see only #if defined(CONFIG_MX31) at this line. Is it your patch correct ? > - setbits_le32(&ehci->control, USB_EN); > - As far as I can see, it tries to overwrite a capability register, that is for our luck read-only. Good catch !
