From a9e632c2ac29c60872e7e4f9314263b34ce5031d Mon Sep 17 00:00:00 2001 From: Eric Biederman Date: Thu, 18 Nov 2004 22:38:08 +0000 Subject: [PATCH] - First stab at getting the ppc ports building and working. - The sandpointx3+altimus has been consolidated into one directory for now. - Added support for having different versions of the pci access functions on a per bus basis if needed. Hopefully I have not broken something inadvertently. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1786 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/arch/i386/boot/linuxbios_table.c | 3 +- src/arch/i386/include/arch/pci_ops.h | 15 +- src/arch/i386/lib/Config.lb | 2 +- src/arch/i386/lib/exception.c | 2 +- src/arch/i386/lib/pci_ops.c | 60 ----- src/arch/i386/lib/pci_ops_auto.c | 45 ++-- src/arch/i386/lib/pci_ops_conf1.c | 19 +- src/arch/i386/lib/pci_ops_conf2.c | 18 +- src/arch/ppc/include/arch/cpu.h | 57 +++++ src/arch/ppc/include/arch/pci_ops.h | 8 +- src/arch/ppc/lib/Config.lb | 4 +- src/arch/ppc/lib/c_start.S | 2 + src/arch/ppc/lib/cpu.c | 29 ++- src/arch/ppc/lib/div64.S | 58 +++++ src/arch/ppc/lib/pci_ops.c | 105 -------- src/arch/ppc/lib/pci_ppc_conf1_ops.c | 46 ++++ src/cpu/ppc/mpc74xx/Config.lb | 2 + src/cpu/ppc/ppc4xx/Config.lb | 1 + src/cpu/ppc/ppc7xx/Config.lb | 2 + src/cpu/simple_init/simple_cpu_init.c | 9 +- src/cpu/x86/lapic/lapic_cpu_init.c | 3 +- src/devices/Config.lb | 1 + src/devices/device_util.c | 18 +- src/devices/pci_device.c | 12 +- src/devices/pci_ops.c | 55 +++++ src/include/arch-generic/div64.h | 2 +- src/include/cpu/cpu.h | 1 + src/include/cpu/ppc/cpuid.h | 2 +- src/include/device/device.h | 8 +- src/include/device/path.h | 25 +- src/include/device/pci.h | 24 +- src/mainboard/motorola/sandpoint/Config.lb | 20 +- .../sandpointx3_altimus_mpc7410/Config.lb | 64 +++++ .../sandpointx3_altimus_mpc7410/Options.lb | 122 ++++++++++ .../sandpointx3_altimus_mpc7410/STATUS | 27 +++ .../sandpointx3_altimus_mpc7410/clock.c | 10 + .../sandpointx3_altimus_mpc7410/flash.h | 35 +++ .../flash/Config.lb | 2 + .../flash/amd800.c | 228 ++++++++++++++++++ .../sandpointx3_altimus_mpc7410/flash/flash.c | 46 ++++ .../sandpointx3_altimus_mpc7410/init.c | 68 ++++++ .../sandpointx3_altimus_mpc7410/nvram.h | 36 +++ .../nvram/Config.lb | 2 + .../nvram/bsp_nvram.c | 54 +++++ .../sandpointx3_altimus_mpc7410/nvram/nvram.c | 101 ++++++++ .../sandpointx3_altimus_mpc7410/sp7410.cfg | 139 +++++++++++ src/mainboard/totalimpact/briq/Config.lb | 22 +- src/northbridge/amd/amdk8/northbridge.c | 2 +- .../emulation/qemu-i386/northbridge.c | 2 +- src/northbridge/ibm/cpc710/Config.lb | 5 +- src/northbridge/ibm/cpc710/chip.h | 6 + .../ibm/cpc710/cpc710_northbridge.c | 103 ++++++++ src/northbridge/intel/e7501/northbridge.c | 5 +- src/northbridge/intel/i855pm/northbridge.c | 2 +- src/northbridge/motorola/mpc107/Config.lb | 5 +- src/northbridge/motorola/mpc107/mpc107.c | 22 -- .../transmeta/tm5800/northbridge.c | 2 +- src/northbridge/via/vt8601/northbridge.c | 2 +- src/northbridge/via/vt8623/northbridge.c | 2 +- src/pc80/keyboard.c | 1 - src/pmc/altimus/mpc7410/Config.lb | 4 +- src/superio/NSC/pc97307/superio.c | 12 +- 62 files changed, 1467 insertions(+), 322 deletions(-) delete mode 100644 src/arch/i386/lib/pci_ops.c create mode 100644 src/arch/ppc/lib/div64.S delete mode 100644 src/arch/ppc/lib/pci_ops.c create mode 100644 src/arch/ppc/lib/pci_ppc_conf1_ops.c create mode 100644 src/devices/pci_ops.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/Config.lb create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/Options.lb create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/STATUS create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/clock.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/flash.h create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/flash/Config.lb create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/flash/amd800.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/flash/flash.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/init.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/nvram.h create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/nvram/Config.lb create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/nvram/bsp_nvram.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/nvram/nvram.c create mode 100644 src/mainboard/motorola/sandpointx3_altimus_mpc7410/sp7410.cfg create mode 100644 src/northbridge/ibm/cpc710/chip.h create mode 100644 src/northbridge/ibm/cpc710/cpc710_northbridge.c diff --git a/src/arch/i386/boot/linuxbios_table.c b/src/arch/i386/boot/linuxbios_table.c index 594b5e55a9..5b2b34ff8a 100644 --- a/src/arch/i386/boot/linuxbios_table.c +++ b/src/arch/i386/boot/linuxbios_table.c @@ -315,7 +315,6 @@ static void build_lb_mem_range(void *gp, struct device *dev, struct resource *re static struct lb_memory *build_lb_mem(struct lb_header *head) { struct lb_memory *mem;
