DS5k/xx code hunting

[Richard van den Berg <R.vandenBerg@inter.NL.net>]

Hi all,

Following is what I encountered hunting down the address in the NetBSD
source where the 5k/xx ethernet hardware address resides. Maybe it is
any help hacking a 5k device driver.

in arch/mips/include/cpuregs.h:

#define MIPS_KSEG1_START                0xa0000000

#define MIPS_PHYS_TO_KSEG1(x)   ((unsigned)(x) | MIPS_KSEG1_START)


in arch/pmax/pmax/maxine.h:

#define XINE_PHYS_TC_3_START    0x1c000000      /* TURBOchannel, slot 3 */
#define XINE_PHYS_TC_3_END      0x1fffffff      /*  64 Meg, system devices */

#define XINE_SYS_ASIC           (XINE_PHYS_TC_3_START + 0x0000000)


in arch/pmax/pmax/machdep.c:

u_long  ioasic_base;            /* Base address of I/O asic */

ioasic_base = MIPS_PHYS_TO_KSEG1(XINE_SYS_ASIC);


in arch/pmax/pmax/asic.h:

#define IOASIC_SLOT_2_START             0x080000

#define IOASIC_SYS_ETHER_ADDRESS(base)  ((base) + IOASIC_SLOT_2_START)


in arch/pmax/tc/asic.c:

ioasic_lance_ether_address()
{

        return (u_char *)IOASIC_SYS_ETHER_ADDRESS(ioasic_base);
}
