Did you mean to submit that against u-boot or Linux? If the latter, there is absolutely no need to have the same file compile under u-boot and Linux without changes, that is too restrictive. There is a genphy_soft_reset() which takes care of waiting for BMCR_RESET to clear, please use it, there is no guarantee otherwise that a PHY has completed a reset. -- Florian -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
