From 6bbc91a96468b97a3e19cdba4641d68e2f2a6f98 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 7 Dec 2017 14:55:51 +0530 Subject: soc/intel/common/block: Add option to have subsystem_id in common pci driver This patch ensures all Intel common PCI devices can have subsystem ID programmed along with PCI resource enabling (.enable_resources) as part of PCI enumeration process. TEST=Build and boot KBL/CNL/APL/GLK to ensure PCI subsystem ID getting programmed. Example: Enabling resources... PCI: 00:00.0 subsystem <- 8086/590c PCI: 00:00.0 cmd <- 06 PCI: 00:02.0 subsystem <- 8086/591e Change-Id: I46307b0db78c8864c85865bd0f3328d5141971be Signed-off-by: Subrata Banik Reviewed-on: https://review.coreboot.org/22768 Reviewed-by: Furquan Shaikh Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin --- src/soc/intel/common/block/cse/cse.c | 1 + src/soc/intel/common/block/dsp/dsp.c | 1 + src/soc/intel/common/block/graphics/graphics.c | 1 + src/soc/intel/common/block/i2c/i2c.c | 1 + src/soc/intel/common/block/lpc/lpc.c | 15 ++++++++------- src/soc/intel/common/block/p2sb/p2sb.c | 1 + src/soc/intel/common/block/pcie/pcie.c | 10 ++++++++++ src/soc/intel/common/block/pmc/pmc.c | 1 + src/soc/intel/common/block/sata/sata.c | 5 +++-- src/soc/intel/common/block/scs/sd.c | 7 ++++--- src/soc/intel/common/block/smbus/smbus.c | 1 + src/soc/intel/common/block/spi/spi.c | 1 + src/soc/intel/common/block/sram/sram.c | 1 + src/soc/intel/common/block/systemagent/systemagent.c | 1 + src/soc/intel/common/block/uart/uart.c | 1 + src/soc/intel/common/block/xdci/xdci.c | 1 + src/soc/intel/common/block/xhci/xhci.c | 1 + 17 files changed, 38 insertions(+), 12 deletions(-) (limited to 'src/soc/intel') diff --git a/src/soc/intel/common/block/cse/cse.c b/src/soc/intel/common/block/cse/cse.c index 77a9b631d9..370074e222 100644 --- a/src/soc/intel/common/block/cse/cse.c +++ b/src/soc/intel/common/block/cse/cse.c @@ -502,6 +502,7 @@ static struct device_operations cse_ops = { .read_resources = pci_dev_read_resources, .enable_resources = pci_dev_enable_resources, .init = pci_dev_init, + .ops_pci = &pci_dev_ops_pci, };
