1 /* 2 * macsonic.c 3 * 4 * (C) 2005 Finn Thain 5 * 6 * Converted to DMA API, converted to unified driver model, made it work as 7 * a module again, and from the mac68k project, introduced more 32-bit cards 8 * and dhd's support for 16-bit cards. 9 * 10 * (C) 1998 Alan Cox 11 * 12 * Debugging Andreas Ehliar, Michael Schmitz 13 * 14 * Based on code 15 * (C) 1996 by Thomas Bogendoerfer (tsbogend@bigbug.franken.de) 16 * 17 * This driver is based on work from Andreas Busse, but most of 18 * the code is rewritten. 19 * 20 * (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de) 21 * 22 * A driver for the Mac onboard Sonic ethernet chip. 23 * 24 * 98/12/21 MSch: judged from tests on Q800, it's basically working, 25 * but eating up both receive and transmit resources 26 * and duplicating packets. Needs more testing. 27 * 28 * 99/01/03 MSch: upgraded to version 0.92 of the core driver, fixed. 29 * 30 * 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems 31 * on centris. 32 */ 33 34 #include <linux/kernel.h> 35 #include <linux/module.h> 36 #include <linux/types.h> 37 #include <linux/fcntl.h> 38 #include <linux/gfp.h> 39 #include <linux/interrupt.h> 40 #include <linux/init.h> 41 #include <linux/ioport.h> 42 #include <linux/in.h> 43 #include <linux/string.h> 44 #include <linux/delay.h> 45 #include <linux/nubus.h> 46 #include <linux/errno.h> 47 #include <linux/netdevice.h> 48 #include <linux/etherdevice.h> 49 #include <linux/skbuff.h> 50 #include <linux/platform_device.h> 51 #include <linux/dma-mapping.h> 52 #include <linux/bitrev.h> 53 #include <linux/slab.h> 54 55 #include <asm/bootinfo.h> 56 #include <asm/system.h> 57 #include <asm/pgtable.h> 58 #include <asm/io.h> 59 #include <asm/hwtest.h> 60 #include <asm/dma.h> 61 #include <asm/macintosh.h> 62 #include <asm/macints.h> 63 #include <asm/mac_via.h> 64 65 static char mac_sonic_string[] = "macsonic"; 66 67 #include "sonic.h" 68 69 /* These should basically be bus-size and endian independent (since 70 the SONIC is at least smart enough that it uses the same endianness 71 as the host, unlike certain less enlightened Macintosh NICs) */ 72 #define SONIC_READ(reg) (nubus_readw(dev->base_addr + (reg * 4) \ 73 + lp->reg_offset)) 74 #define SONIC_WRITE(reg,val) (nubus_writew(val, dev->base_addr + (reg * 4) \ 75 + lp->reg_offset)) 76 77 /* use 0 for production, 1 for verification, >1 for debug */ 78 #ifdef SONIC_DEBUG 79 static unsigned int sonic_debug = SONIC_DEBUG; 80 #else 81 static unsigned int sonic_debug = 1; 82 #endif 83 84 static int sonic_version_printed; 85 86 /* For onboard SONIC */ 87 #define ONBOARD_SONIC_REGISTERS 0x50F0A000 88 #define ONBOARD_SONIC_PROM_BASE 0x50f08000 89 90 enum macsonic_type { 91 MACSONIC_DUODOCK, 92 MACSONIC_APPLE, 93 MACSONIC_APPLE16, 94 MACSONIC_DAYNA, 95 MACSONIC_DAYNALINK 96 }; 97 98 /* For the built-in SONIC in the Duo Dock */ 99 #define DUODOCK_SONIC_REGISTERS 0xe10000 100 #define DUODOCK_SONIC_PROM_BASE 0xe12000 101 102 /* For Apple-style NuBus SONIC */ 103 #define APPLE_SONIC_REGISTERS 0 104 #define APPLE_SONIC_PROM_BASE 0x40000 105 106 /* Daynalink LC SONIC */ 107 #define DAYNALINK_PROM_BASE 0x400000 108 109 /* For Dayna-style NuBus SONIC (haven't seen one yet) */ 110 #define DAYNA_SONIC_REGISTERS 0x180000 111 /* This is what OpenBSD says.
