All IO peripherals in +Topcliff PCH are actually devices sitting on AMBA bus. Packet hub is +a special converter device in Topcliff PCH that translate AMBA transactions +to PCI Express transactions and vice versa. Thus packet hub helps present +all IO peripherals in Topcliff PCH as PCIE devices to IA system. +Topcliff PCH has MAC address and Option ROM data. +These data are in SROM which is connected to PCIE bus. +Packet hub driver of Topcliff PCH can access MAC address and Option ROM data in +SROM via sysfs interface. + + +Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> +--- + Documentation/ABI/testing/sysfs-module | 12 + drivers/misc/Kconfig | 12 + drivers/misc/Makefile | 1 + drivers/misc/pch_phub.c | 717 +++++++++++++++++++++++++++++++++ + 4 files changed, 742 insertions(+) + +--- /dev/null ++++ b/Documentation/ABI/testing/sysfs-module +@@ -0,0 +1,12 @@ ++What: /sys/module/pch_phub/drivers/.../pch_mac ++Date: August 2010 ++KernelVersion: 2.6.35 ++Contact: masa-korg@dsn.okisemi.com ++Description: Write/read GbE MAC address. ++ ++What: /sys/module/pch_phub/drivers/.../pch_firmware ++Date: August 2010 ++KernelVersion: 2.6.35 ++Contact: masa-korg@dsn.okisemi.com ++Description: Write/read Option ROM data. ++ +--- a/drivers/misc/Kconfig ++++ b/drivers/misc/Kconfig +@@ -390,6 +390,18 @@ config BMP085 + To compile this driver as a module, choose M here: the + module will be called bmp085. + ++config PCH_PHUB ++ tristate "PCH Packet Hub of Intel Topcliff" ++ depends on PCI ++ help ++ This driver is for PCH(Platform controller Hub) PHUB(Packet Hub) of ++ Intel Topcliff which is an IOH(Input/Output Hub) for x86 embedded ++ processor.
