* | | x86: Unify 3 similar ways of saving mp_irqs infoFeng Tang2010-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 3 places defining similar functions of saving IRQ vector info into mp_irqs[] array: mmparse/acpi/mrst. Replace the redundant code by a common function in io_apic.c as it's only called when CONFIG_X86_IO_APIC=y Signed-off-by: Feng Tang <feng.tang@intel.com> Cc: Alan Cox <alan@linux.intel.com> Cc: Len Brown <len.brown@intel.com> Cc: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <20101207133204.4d913c5a@feng-i7> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * ce4100: Add errata fixes for UART on CE4100Dirk Brandewie2010-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the UART on the CE4100. The UART has a couple of issues that need to be worked around. First the UART is mostly PC compatible except that it is clocked eight times faster than a standard PC so the default configuration provided in arch/x86/include/asm/serial.h needs to be overridden. Second the TX interrupt may not be set correctly all the time. Lastly accessing the UART via I/O space for early_prink() hangs the chip when the IOAPIC is enabled. A custom mem_serial_in() is provided to work around the TX interrupt issue. The configuration issues are dealt with in the call back registered with the 8250 driver via serial8250_set_isa_configurator() Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> LKML-Reference: <1290436128-17958-1-git-send-email-dirk.brandewie@gmail.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * x86: mrst: Set vRTC's IRQ to level trigger typeFeng Tang2010-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting up the mpc_intsrc structure for vRTC's IRQ, we need to set its irqflag to level trigger, otherwise it will be taken as edge triggered and the vRTC IRQ will fire only once, as there is never a EOI issued from the IA core for it. The original code worked in previous kernel. This is because it was configured to level trigger type by luck. It fell into the default PCI trigger category which is level triggered.

| * x86: mrst: Parse SFI timer table for all timer configsJacob Pan2010-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Penwell has APB timer based watchdog timers, it requires platform code to parse SFI MTMR tables in order to claim its timer. This patch will always parse SFI MTMR regardless of system timer configuration choices. Otherwise, SFI MTMR table may not get parsed if running on Medfield with always-on local APIC timers and constant TSC. Watchdog timer driver will then not get a timer to use.

| * x86/mrst: Add SFI platform device parsing codeFeng Tang2010-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* x86: Add platform directoryThomas Gleixner2010-10-27
x86 has finally arrived in the embedded nightmare and will rapidly grow SoC platform support in various flavours. So we need a place for the platform support files. That also allows us to clean up the dumpground which arch/x86/kernel has become over time. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
