23 * File Name: enetemac.c
25 * Function: Device driver for the ethernet EMAC3 macro on the 405GP.
31 * Date Description of Change BY
32 * --------- --------------------- ---
33 * 05-May-99 Created MKW
34 * 27-Jun-99 Clean up JWB
35 * 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
36 * 29-Jul-99 Added Full duplex support MKW
37 * 06-Aug-99 Changed names for Mal CR reg MKW
38 * 23-Aug-99 Turned off SYE when running at 10Mbs MKW
39 * 24-Aug-99 Marked descriptor empty after call_xlc MKW
40 * 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG
41 * to avoid chaining maximum sized packets. Push starting
42 * RX descriptor address up to the next cache line boundary.
43 * 16-Jan-00 Added support for booting with IP of 0x0 MKW
44 * 15-Mar-00 Updated enetInit() to enable broadcast addresses in the
45 * EMAC_RXM register. JWB
46 * 12-Mar-01 anne-sophie.harnois@nextream.fr
47 * - Variables are compatible with those already defined in
49 * - Receive buffer descriptor ring is used to send buffers
51 * - Info print about send/received/handled packet number if
52 * INFO_405_ENET is set
53 * 17-Apr-01 stefan.roese@esd-electronics.com
54 * - MAL reset in "eth_halt" included
55 * - Enet speed and duplex output now in one line
56 * 08-May-01 stefan.roese@esd-electronics.com
57 * - MAL error handling added (eth_init called again)
58 * 13-Nov-01 stefan.roese@esd-electronics.com
59 * - Set IST bit in EMAC_M1 reg upon 100MBit or full duplex
60 * 04-Jan-02 stefan.roese@esd-electronics.com
61 * - Wait for PHY auto negotiation to complete added
62 * 06-Feb-02 stefan.roese@esd-electronics.com
63 * - Bug fixed in waiting for auto negotiation to complete
64 * 26-Feb-02 stefan.roese@esd-electronics.com
65 * - rx and tx buffer descriptors now allocated (no fixed address
67 * 17-Jun-02 stefan.roese@esd-electronics.com
68 * - MAL error debug printf 'M' removed (rx de interrupt may
69 * occur upon many incoming packets with only 4 rx buffers).
70 *-----------------------------------------------------------------------------*
71 * 17-Nov-03 travis.sawyer@sandburst.com
72 * - ported from 405gp_enet.c to utilized upto 4 EMAC ports
73 * in the 440GX. This port should work with the 440GP
75 * 15-Aug-05 sr@denx.de
76 * - merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
77 now handling all 4xx cpu's.
