From e77beeccf54d23cd429572966814704a7fd08e4f Mon Sep 17 00:00:00 2001 From: aaron Date: Sat, 8 Apr 2000 05:50:49 +0000 Subject: [PATCH] Initial check-in for support of 32-bit CardBus PC Cards; from NetBSD. On many machines, this code needs the new PCIBIOS* options enabled in the kernel config file to work, but your mileage may vary. Included is a working 3c575 driver for 3Com 10/100 CardBus PC Card NICs (tested only with the 'C' revision). The 3c575 is the pccard version of the PCI EtherLink XL cards, and thus the xl driver has been split into /sys/dev/ic. --- sys/arch/i386/conf/GENERIC | 9 +- sys/arch/i386/conf/files.i386 | 10 +- sys/arch/i386/i386/machdep.c | 25 +- sys/arch/i386/i386/rbus_machdep.c | 163 ++ sys/arch/i386/include/bus.h | 5 +- sys/arch/i386/include/rbus_machdep.h | 53 + sys/conf/files | 9 +- sys/dev/cardbus/cardbus.c | 934 +++++++ sys/dev/cardbus/cardbus_exrom.c | 183 ++ sys/dev/cardbus/cardbus_exrom.h | 73 + sys/dev/cardbus/cardbus_map.c | 442 ++++ sys/dev/cardbus/cardbusvar.h | 450 ++++ sys/dev/cardbus/cardslot.c | 439 ++++ sys/dev/cardbus/cardslotvar.h | 125 + sys/dev/cardbus/files.cardbus | 51 + sys/dev/cardbus/if_xl_cardbus.c | 426 ++++ sys/dev/cardbus/rbus.c | 387 +++ sys/dev/cardbus/rbus.h | 166 ++ sys/dev/ic/i82365.c | 157 +- sys/dev/ic/i82365var.h | 43 +- sys/dev/{pci/if_xl.c => ic/xl.c} | 239 +- sys/dev/{pci/if_xlreg.h => ic/xlreg.h} | 14 +- sys/dev/isa/i82365_isasubr.c | 10 +- sys/dev/pci/files.pci | 13 +- sys/dev/pci/if_xl_pci.c | 225 ++ sys/dev/pci/pccbb.c | 3100 ++++++++++++++++++++++++ sys/dev/pci/pccbbreg.h | 225 ++ sys/dev/pci/pccbbvar.h | 174 ++ sys/dev/pcmcia/files.pcmcia | 4 +- sys/dev/pcmcia/pcmcia.c | 8 +- sys/dev/pcmcia/pcmciachip.h | 13 +- sys/kern/Makefile | 6 +- 32 files changed, 7897 insertions(+), 284 deletions(-) create mode 100644 sys/arch/i386/i386/rbus_machdep.c create mode 100644 sys/arch/i386/include/rbus_machdep.h create mode 100644 sys/dev/cardbus/cardbus.c create mode 100644 sys/dev/cardbus/cardbus_exrom.c create mode 100644 sys/dev/cardbus/cardbus_exrom.h create mode 100644 sys/dev/cardbus/cardbus_map.c create mode 100644 sys/dev/cardbus/cardbusvar.h create mode 100644 sys/dev/cardbus/cardslot.c create mode 100644 sys/dev/cardbus/cardslotvar.h create mode 100644 sys/dev/cardbus/files.cardbus create mode 100644 sys/dev/cardbus/if_xl_cardbus.c create mode 100644 sys/dev/cardbus/rbus.c create mode 100644 sys/dev/cardbus/rbus.h rename sys/dev/{pci/if_xl.c => ic/xl.c} (91%) rename sys/dev/{pci/if_xlreg.h => ic/xlreg.h} (97%) create mode 100644 sys/dev/pci/if_xl_pci.c create mode 100644 sys/dev/pci/pccbb.c create mode 100644 sys/dev/pci/pccbbreg.h create mode 100644 sys/dev/pci/pccbbvar.h diff --git a/sys/arch/i386/conf/GENERIC b/sys/arch/i386/conf/GENERIC index 8e2b6c63234..d1d635cbfa4 100644 --- a/sys/arch/i386/conf/GENERIC +++ b/sys/arch/i386/conf/GENERIC @@ -1,4 +1,4 @@ -# $OpenBSD: GENERIC,v 1.174 2000/04/07 22:25:43 aaron Exp $ +# $OpenBSD: GENERIC,v 1.175 2000/04/08 05:50:49 aaron Exp $ # $NetBSD: GENERIC,v 1.48 1996/05/20 18:17:23 mrg Exp $ # # GENERIC -- everything that's currently supported @@ -64,6 +64,12 @@ pcic2 at isa? port 0x3e4 iomem 0xe0000 iosiz 0x4000 # PCMCIA bus support pcmcia* at pcic? controller ? socket ? +# CardBus bus support +#cardbus* at cardslot? +#pcmcia* at cardslot? +#cbb* at pci? dev ? function ? +#cardslot* at cbb? + # PCI USB Controllers #uhci* at pci? # Universal Host Controller (Intel) #ohci* at pci? # Open Host Controller @@ -260,6 +266,7 @@ sm* at pcmcia? function ? # PCMCIA based sm ethernet xe* at pcmcia? function ? # Xircom ethernet fpa* at pci? dev ? function ? # DEC DEFPA FDDI xl* at pci? dev ? function ? # 3c9xx ethernet +#xl* at cardbus? dev ? function ? # 3c575 ethernet rl* at pci? dev ? function ? # RealTek 81[23]9 ethernet tx* at pci? dev ? function ? # SMC 83C170 EPIC ethernet tl* at pci? dev ? function ? # Compaq Thunderlan ethernet diff --git a/sys/arch/i386/conf/files.i386 b/sys/arch/i386/conf/files.i386 index 809930770b0..778c72658c1 100644 --- a/sys/arch/i386/conf/files.i386 +++ b/sys/arch/i386/conf/files.i386 @@ -1,4 +1,4 @@ -# $OpenBSD: files.i386,v 1.63 2000/03/26 22:38:32 mickey Exp $ +# $OpenBSD: files.i386,v 1.64 2000/04/08 05:50:49 aaron Exp $ # $NetBSD: files.i386,v 1.73 1996/05/07 00:58:36 thorpej Exp $ # # new style config file for i386 architecture @@ -255,6 +255,12 @@ file arch/i386/i386/apmcall.S apm file arch/i386/i386/bios32.c bios32 +# +# CARDBUS +# +include "dev/cardbus/files.cardbus" +file arch/i386/i386/rbus_machdep.c cardbus + # XXXX pcic here because it needs to be late.
