Jacob Pan 064a59b6dd x86/mrst: Avoid reporting wrong nmi status
Moorestown/Medfield platform does not have port 0x61 to report
NMI status, nor does it have external NMI sources. The only NMI
sources are from lapic, as results of perf counter overflow or
IPI, e.g. NMI watchdog or spin lock debug.

Reading port 0x61 on Moorestown will return 0xff which misled
NMI handlers to false critical errors such memory parity error.
The subsequent ioport access for NMI handling can also cause
undefined behavior on Moorestown.

This patch allows kernel process NMI due to watchdog or backrace
dump without unnecessary hangs.

Mika Westerberg 153b19a3b9 x86, mrst: use a temporary variable for SFI irq
SFI tables reside in RAM and should not be modified once they are
written.  Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum.  This will
break kexec as the second kernel fails to validate SFI tables.

To fix this we use temporary variable for irq number.

Kirill A. Shutemov a94cc4e6c0 sfi: table irq 0xFF means 'no interrupt'
According to the SFI specification irq number 0xFF means device has no
interrupt or interrupt attached via GPIO.

Currently, we don't handle this special case and set irq field in
*_board_info structs to 255.  It leads to confusion in some drivers.
Accelerometer driver tries to register interrupt 255, fails and prints
"Cannot get IRQ" to dmesg.

Jacob Pan 9d90e49da5 x86/mrst: Fix boot crash caused by incorrect pin to irq mapping
Moorestown systems crash on boot because the secondary CPU
clockevent (apbt1) will fail to request irq#1, which does not
have ioapic chip in its irq_desc[] entry.

Background:

Moorestown platform does not have ISA bus nor legacy IRQs. It
reuses the range of legacy IRQs for regular device interrupts.
The routing information of early system device IRQs (timers) are
obtained from firmware provided SFI tables. We reuse/fake MP
configuration table to facilitate IRQ setup with IOAPIC.

Maintaining a 1:1 mapping of IOAPIC pin (RTE entry) and IRQ#
makes routing information clean and easy to understand on
Moorestown. Though optional.

This patch allows SFI timer and vRTC IRQ to be treated as ISA
IRQ so that pin2irq mapping will be 1:1.

Also fixed MP table type and use macros to clearly set MP IRQ
entries. As a result, apbt timer and RTC interrupts on
Moorestown are within legacy IRQ range:

 # cat /proc/interrupts
            CPU0       CPU1
   0:      11249          0   IO-APIC-edge      apbt0
   1:          0      12271   IO-APIC-edge      apbt1
   8:        887          0   IO-APIC-fasteoi   dw_spi
  13:          0          0   IO-APIC-fasteoi   INTEL_MID_DMAC2
  14:          0          0   IO-APIC-fasteoi   rtc0

Feng Tang 6f207e9bb4 x86: mrst: Set vRTC's IRQ to level trigger type
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.

Feng Tang 1da4b1c6a4 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)
