6 * File Name: enetemac.c

8 * Function: Device driver for the ethernet EMAC3 macro on the 405GP.
9 *
10 * Author: Mark Wisner
11 *
12 * Change Activity-
13 *
14 * Date Description of Change BY
15 * --------- --------------------- ---
16 * 05-May-99 Created MKW
17 * 27-Jun-99 Clean up JWB
18 * 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
19 * 29-Jul-99 Added Full duplex support MKW
20 * 06-Aug-99 Changed names for Mal CR reg MKW
21 * 23-Aug-99 Turned off SYE when running at 10Mbs MKW
22 * 24-Aug-99 Marked descriptor empty after call_xlc MKW
23 * 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG
24 * to avoid chaining maximum sized packets. Push starting
25 * RX descriptor address up to the next cache line boundary.
26 * 16-Jan-00 Added support for booting with IP of 0x0 MKW
27 * 15-Mar-00 Updated enetInit() to enable broadcast addresses in the
28 * EMAC0_RXM register. JWB
29 * 12-Mar-01 anne-sophie.harnois@nextream.fr
30 * - Variables are compatible with those already defined in
31 * include/net.h
32 * - Receive buffer descriptor ring is used to send buffers
33 * to the user
34 * - Info print about send/received/handled packet number if
35 * INFO_405_ENET is set
36 * 17-Apr-01 stefan.roese@esd-electronics.com
37 * - MAL reset in "eth_halt" included
38 * - Enet speed and duplex output now in one line
39 * 08-May-01 stefan.roese@esd-electronics.com
40 * - MAL error handling added (eth_init called again)
41 * 13-Nov-01 stefan.roese@esd-electronics.com
42 * - Set IST bit in EMAC0_MR1 reg upon 100MBit or full duplex
43 * 04-Jan-02 stefan.roese@esd-electronics.com
44 * - Wait for PHY auto negotiation to complete added
45 * 06-Feb-02 stefan.roese@esd-electronics.com
46 * - Bug fixed in waiting for auto negotiation to complete
47 * 26-Feb-02 stefan.roese@esd-electronics.com
48 * - rx and tx buffer descriptors now allocated (no fixed address
49 * used anymore)
50 * 17-Jun-02 stefan.roese@esd-electronics.com
51 * - MAL error debug printf 'M' removed (rx de interrupt may
52 * occur upon many incoming packets with only 4 rx buffers).
53 *-----------------------------------------------------------------------------*
54 * 17-Nov-03 travis.sawyer@sandburst.com
55 * - ported from 405gp_enet.c to utilized upto 4 EMAC ports
56 * in the 440GX. This port should work with the 440GP
57 * (2 EMACs) also
58 * 15-Aug-05 sr@denx.de
59 * - merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
60 now handling all 4xx cpu's.
