x86/mrst: Add SFI platform device parsing code
SFI provides a series of tables. These describe the platform devices present including SPI and I²C devices, as well as various sensors, keypads and other glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c) This patch is a merge of the core elements and relevant fixes from the Intel development code by Feng, Alek, myself into a single coherent patch for upstream submission. It provides the needed infrastructure to register I2C, SPI and platform devices described by the tables, as well as handlers for some of the hardware already supported in kernel. The 0.8 firmware also provides GPIO tables. Devices are created at boot time or if they are SCU dependant at the point an SCU is discovered. The existing Linux device mechanisms will then handle the device binding. At an abstract level this is an SFI to Linux device translator. Device/platform specific setup/glue is in this file. This is done so that the drivers for the generic I²C and SPI bus devices remain cross platform as they should. (Updated from RFC version to correct the emc1403 name used by the firmware and a wrongly used #define) Signed-off-by: Alek Du <alek.du@linux.intel.com> LKML-Reference: <20101109112158.20013.6158.stgit@localhost.localdomain> [Clean ups, removal of 0.7 support] Signed-off-by: Feng Tang <feng.tang@linux.intel.com> [Clean ups] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
