The controller itself is automatically detected by bcma. - -This controller is found on SoCs usually used in SOHO routers to -connect the wifi cards to the SoC. All the of the BCM5301X SoCs I know -of have 2 or 3 of these controllers in the SoC. - -I had to use PCI domains otherwise the pci_create_root_bus() function -in drivers/pci/probe.c would fail for the second controller being -registered because pci_find_bus() would find the same PCIe bus again -and assume it is already registered, which ends up in a kernel panic in -pcibios_init_hw() in arch/arm/kernel/bios32.c - -The ARM PCI code assumes that every controller has an I/O space and -adds a dummy area if the driver does not specify one. This will work -for the first controller, but when we register the second one this will -result in an error. To prevent this problem we add an empty I/O space. - -Currently I have problems with probing the devices on the bus, because -pci_bus_add_devices() is called too early in pci_scan_root_bus() in -drivers/pci/probe.c, before pci_bus_assign_resources() was called in -pci_common_init_dev() in arch/arm/kernel/bios32.c. When the devices are -added too early they do not have any resources and adding fails. I have -to remove the call to pci_bus_add_devices() in pci_scan_root_bus() to -make registration work, calling pci_bus_add_devices() later again does -not fix this problem. - -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> ---- - arch/arm/mach-bcm/Kconfig | 1 + - drivers/pci/host/Kconfig | 7 + - drivers/pci/host/Makefile | 1 + - drivers/pci/host/pci-host-bcm5301x.c | 428 +++++++++++++++++++++++++++++++++++ - 4 files changed, 437 insertions(+) - create mode 100644 drivers/pci/host/pci-host-bcm5301x.c - ---- a/arch/arm/mach-bcm/Kconfig -+++ b/arch/arm/mach-bcm/Kconfig -@@ -45,6 +45,7 @@ config ARCH_BCM_5301X - select ARM_GLOBAL_TIMER - select CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK - select MIGHT_HAVE_PCI -+ select PCI_DOMAINS if PCI - help - Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores. - ---- a/drivers/pci/host/Kconfig -+++ b/drivers/pci/host/Kconfig -@@ -33,4 +33,11 @@ config PCI_RCAR_GEN2 - There are 3 internal PCI controllers available with a single - built-in EHCI/OHCI host controller present on each one. - -+config PCI_BCM5301X -+ bool "BCM5301X PCIe2 host controller" -+ depends on BCMA && OF && ARM && PCI_DOMAINS -+ help -+ Say Y here if you want to support the PCIe host controller found -+ on Broadcom BCM5301X and BCM470X (Northstar) SoCs. -+ - endmenu ---- a/drivers/pci/host/Makefile -+++ b/drivers/pci/host/Makefile -@@ -4,3 +4,4 @@ obj-$(CONFIG_PCI_IMX6) += pci-imx6.o - obj-$(CONFIG_PCI_MVEBU) += pci-mvebu.o - obj-$(CONFIG_PCI_TEGRA) += pci-tegra.o - obj-$(CONFIG_PCI_RCAR_GEN2) += pci-rcar-gen2.o -+obj-$(CONFIG_PCI_BCM5301X) += pci-host-bcm5301x.o ---- /dev/null -+++ b/drivers/pci/host/pci-host-bcm5301x.c -@@ -0,0 +1,460 @@ -+/* -+ * Northstar PCI-Express driver -+ * Only supports Root-Complex (RC) mode -+ * -+ * Notes: -+ * PCI Domains are being used to identify the PCIe port 1:1. -+ * -+ * Only MEM access is supported, PAX does not support IO. -+ * -+ * Copyright 2012-2014, Broadcom Corporation -+ * Copyright 2014, Hauke Mehrtens <hauke@hauke-m.de> -+ * -+ * Licensed under the GNU/GPL.
