25 * File Name: enetemac.c
27 * Function: Device driver for the ethernet EMAC3 macro on the 405GP.
33 * Date Description of Change BY
34 * --------- --------------------- ---
35 * 05-May-99 Created MKW
36 * 27-Jun-99 Clean up JWB
37 * 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
38 * 29-Jul-99 Added Full duplex support MKW
39 * 06-Aug-99 Changed names for Mal CR reg MKW
40 * 23-Aug-99 Turned off SYE when running at 10Mbs MKW
41 * 24-Aug-99 Marked descriptor empty after call_xlc MKW
42 * 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG
43 * to avoid chaining maximum sized packets. Push starting
44 * RX descriptor address up to the next cache line boundary.
45 * 16-Jan-00 Added support for booting with IP of 0x0 MKW
46 * 15-Mar-00 Updated enetInit() to enable broadcast addresses in the
47 * EMAC_RXM register. JWB
48 * 12-Mar-01 anne-sophie.harnois@nextream.fr
49 * - Variables are compatible with those already defined in
51 * - Receive buffer descriptor ring is used to send buffers
53 * - Info print about send/received/handled packet number if
54 * INFO_405_ENET is set
55 * 17-Apr-01 stefan.roese@esd-electronics.com
56 * - MAL reset in "eth_halt" included
57 * - Enet speed and duplex output now in one line
58 * 08-May-01 stefan.roese@esd-electronics.com
59 * - MAL error handling added (eth_init called again)
60 * 13-Nov-01 stefan.roese@esd-electronics.com
61 * - Set IST bit in EMAC_M1 reg upon 100MBit or full duplex
62 * 04-Jan-02 stefan.roese@esd-electronics.com
63 * - Wait for PHY auto negotiation to complete added
64 * 06-Feb-02 stefan.roese@esd-electronics.com
65 * - Bug fixed in waiting for auto negotiation to complete
66 * 26-Feb-02 stefan.roese@esd-electronics.com
67 * - rx and tx buffer descriptors now allocated (no fixed address
69 * 17-Jun-02 stefan.roese@esd-electronics.com
70 * - MAL error debug printf 'M' removed (rx de interrupt may
71 * occur upon many incoming packets with only 4 rx buffers).
72 *-----------------------------------------------------------------------------*
73 * 17-Nov-03 travis.sawyer@sandburst.com
74 * - ported from 405gp_enet.c to utilized upto 4 EMAC ports
75 * in the 440GX. This port should work with the 440GP
77 * 15-Aug-05 sr@denx.de
78 * - merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
79 now handling all 4xx cpu's.
