The definition of the framebuffer parameters was created when s3c-fb.c
driver was patched to support setting the refresh rate directly (commit
600ce1a0fa). That patch was completely wrong
and was reverted in commit eb29a5cc0b what breaked the
framebuffer on s5pc100. This patch updates framebuffer definitions to
correct values.

Add support for the sh7372 INTCS interrupt controller.
INTCS is the interrupt controller for the sh7372 SuperH
processor core. It is tied into the INTCA interrupt
controller which interfaces to the ARM processor.
INTCS support is implemented using a new INTC table
together with a chained interrupt handler that ties
into the already supported INTCA controller.

Change INTCS_VECT_BASE from 0x3400 to 0x2200.
The old value 0x3400 gave the INTCA and INTCS interrupt
conrollers separated spaces, but required ARM support
for more than 512 NR_IRQS which is not in place at this
point.
The value 0x2200 will make some of the INTCA interrupts
make use of empty INTCS areas. This is a bit more error
prone but works fine as a workaround for G3, G3 and AP4.

Traditionally, fatal MCE will cause Linux print error log to console
then reboot. Because MCE registers will preserve their content after
warm reboot, the hardware error can be logged to disk or network after
reboot. But system may fail to warm reboot, then you may lose the
hardware error log. ERST can help here. Through saving the hardware
error log into flash via ERST before go panic, the hardware error log
can be gotten from the flash after system boot successful again.
The fatal MCE processing procedure with ERST involved is as follow:
- Hardware detect error, MCE raised
- MCE read MCE registers, check error severity (fatal), prepare error record
- Write MCE error record into flash via ERST
- Go panic, then trigger system reboot
- System reboot, /sbin/mcelog run, it reads /dev/mcelog to check flash
for error record of previous boot via ERST, and output and clear
them if available
- /sbin/mcelog logs error records into disk or network
ERST only accepts CPER record format, but there is no pre-defined CPER
section can accommodate all information in struct mce, so a customized
section type is defined to hold struct mce inside a CPER record as an
error section.

Generic Hardware Error Source provides a way to report platform
hardware errors (such as that from chipset). It works in so called
"Firmware First" mode, that is, hardware errors are reported to
firmware firstly, then reported to Linux by firmware. This way, some
non-standard hardware error registers or non-standard hardware link
can be checked by firmware to produce more valuable hardware error
information for Linux.
Now, only SCI notification type and memory errors are supported. More
notification type and hardware error type will be added later. These
memory errors are reported to user space through /dev/mcelog via
faking a corrected Machine Check, so that the error memory page can be
offlined by /sbin/mcelog if the error count for one page is beyond the
threshold.
On some machines, Machine Check can not report physical address for
some corrected memory errors, but GHES can do that. So this simplified
GHES is implemented firstly.

While waiting for completion of the i2c transfer, the
MPU could hit OFF mode and cause several msecs of
delay that made i2c transfers fail more often. The
extra delays and subsequent re-trys cause i2c clocks
to be active more often. This has also an negative
effect on power consumption.
Created a mechanism for passing and using the
constraint setting function in driver code. The used
mpu wake up latency constraints are now set individually
per bus, and they are calculated based on clock rate
and fifo size.
Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley,
and Nishanth Menon for tuning out the details of
this patch.
Updates by Kevin as requested by Tony:
- Remove omap_set_i2c_constraint_func() in favor of conditionally
adding the flag in omap_i2c_add_bus() in order to keep all the OMAP
conditional checking in a single location.
- Update set_mpu_wkup_lat prototypes to match OMAP PM layer so
OMAP PM function can be used directly in pdata.

Always-on local APIC timer (ARAT) has been introduced to Medfield, along
with the platform APB timers we have more timer configuration options
between Moorestown and Medfield.
This patch adds run-time detection of avaiable timer features so that
we can treat Medfield as a variant of Moorestown and set up the optimal
timer options for each platform. i.e.
Medfield: per cpu always-on local APIC timer
Moorestown: per cpu APB timer
Manual override is possible via cmdline option x86_mrst_timer.
