+ *
+ * Author: Mark Wisner
+ *
+ * Change Activity-
+ *
+ * Date Description of Change BY
+ * --------- --------------------- ---
+ * 05-May-99 Created MKW
+ * 27-Jun-99 Clean up JWB
+ * 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
+ * 29-Jul-99 Added Full duplex support MKW
+ * 06-Aug-99 Changed names for Mal CR reg MKW
+ * 23-Aug-99 Turned off SYE when running at 10Mbs MKW
+ * 24-Aug-99 Marked descriptor empty after call_xlc MKW
+ * 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG
+ * to avoid chaining maximum sized packets. Push starting
+ * RX descriptor address up to the next cache line boundary.
+ * 16-Jan-00 Added support for booting with IP of 0x0 MKW
+ * 15-Mar-00 Updated enetInit() to enable broadcast addresses in the
+ * EMAC_RXM register. JWB
+ * 12-Mar-01 anne-sophie.harnois@nextream.fr
+ * - Variables are compatible with those already defined in
+ * include/net.h
+ * - Receive buffer descriptor ring is used to send buffers
+ * to the user
+ * - Info print about send/received/handled packet number if
+ * INFO_405_ENET is set
+ * 17-Apr-01 stefan.roese@esd-electronics.com
+ * - MAL reset in "eth_halt" included
+ * - Enet speed and duplex output now in one line
+ * 08-May-01 stefan.roese@esd-electronics.com
+ * - MAL error handling added (eth_init called again)
+ * 13-Nov-01 stefan.roese@esd-electronics.com
+ * - Set IST bit in EMAC_M1 reg upon 100MBit or full duplex
+ * 04-Jan-02 stefan.roese@esd-electronics.com
+ * - Wait for PHY auto negotiation to complete added
+ * 06-Feb-02 stefan.roese@esd-electronics.com
+ * - Bug fixed in waiting for auto negotiation to complete
+ * 26-Feb-02 stefan.roese@esd-electronics.com
+ * - rx and tx buffer descriptors now allocated (no fixed address
+ * used anymore)
+ * 17-Jun-02 stefan.roese@esd-electronics.com
+ * - MAL error debug printf 'M' removed (rx de interrupt may
+ * occur upon many incoming packets with only 4 rx buffers).
+ *-----------------------------------------------------------------------------*
+ * 17-Nov-03 travis.sawyer@sandburst.com
+ * - ported from 405gp_enet.c to utilized upto 4 EMAC ports
+ * in the 440GX. This port should work with the 440GP
+ * (2 EMACs) also

+ XES XPedite1000 Board
+
+ Last Update: December 29, 2003
+=======================================================================
+
+This file contains some handy info regarding U-Boot and the XES
+XPedite1000 PPC440GX PrPMC board. See the README.ppc440 for additional
+information.
+
+
+SWITCH SETTINGS & JUMPERS
+==========================
+
+Jumpers selected for AMD29LV040B flash part as the boot flash.
+
+
+I2C Strap EEPROM & Environment Settings
+=======================================
+
+The XPedite1000 uses a single I2C eeprom for the 440 strappings and for
+the environment variables. The first page (256 bytes) contains the
+strappings and the 2 EMAC HW Ethernet addresses. Be careful not to
+change the 1st page of the EEPROM! Unpopulated jumper J560 can get you
+out of trouble as it disables the strapping read from EEPROM.
+
+I2C iprobe
+=====================
+
+The i2c utilities work and have been tested on Rev B. of the 440GX. See
+README.ebony for more information about i2c probing with the 440.
+
+
+GETTING OUT OF I2C TROUBLE
+===========================
+
+(Direct quote from README.ebony)
+If you're like me ... you may have screwed up your bootstrap serial
+eeprom ... or worse, your SPD eeprom when experimenting with the
+i2c commands. If so, here are some ideas on how to get out of
+trouble:
+
+Serial bootstrap eeprom corruption:
+-----------------------------------
+Power down the board and set the following straps:
+
+J560 - closed
+
+This will select the default sys0 and sys1 settings (the serial
+eeproms are not used). Then power up the board and fix the serial
+eeprom using the imm command. Here are the values I currently
+use:
+
+=> imd 50 0 10
+
+0000: 85 7d 42 06 07 80 11 00 00 00 00 00 00 00 00 00 .}B.............
+
+Once you have the eeproms set correctly change the
+J560 straps as you desire.
+
+
+PPC440GX Ethernet EMACs
+=======================
+
+The XES XPedite1000 uses emac 2 & 3 and ignores emac 0 & 1. PHYs are connected
+only to emac 2 & 3. The HW Ethernet addresses are read from the i2c eeprom and
+placed in the bd info structure for enet2addr and enet3addr. The ethernet driver
+senses that enetaddr and enet1addr are 0's and does not use them.
+
+As of this writing gigabit ethernet and the TCPIP acceleration hardware is not
+supported.
+
+
+Flash Support
+=============
+
+As of this writing, there is support for the 1/2mb boot flash only. User flash
+is not yet supported.
+
+
+Regards,
+--Travis
