* net: Multiple updates/enhancements to designware.cStefan Roese2012-07-07-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.

* SPEAr: Add interface information in initializationVipin Kumar2012-07-07-0/+1
| | | | | | | | | | Few Designware peripheral registers need to be modified based on the ethernet interface selected by the board. This patch supports interface information in ethernet driver Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Stefan Roese <sr@denx.de>
* net/designware: Try configuring phy on each dw_eth_initVipin Kumar2012-04-04-0/+1
| | | | | | | | | | | | | Phy autonegotiation works only when the ethernet cable is plugged in. Since the phy was configured only at the init time, a plugged in cable was necessary to initialize the phy properly. This patch keeps a flag to check if the phy initialization has succeeded, and calls configure_phy routine at every init if this flag reports otherwise.

* net/designware: Fix the max frame length sizeVipin KUMAR2012-04-04-1/+1
| | | | | | | | | The max frame length for normal descriptor can be 0x7FF i.e 2047. It was wrongly specified as 2048. Currently, the max descriptor length is around 1500, so redefining the mask to 1600 Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>
