The driver provides the information regarding the ocp errors
that gets logged in the interconnect.The error info provides
the details regarding the master or the target that
generated the error, type of error and the corresponding address.
The stack dump is also provided.

Use straight 64-bit values as 64-bit operations are fairly efficient on ARM.
Comparing the asm output with and without KTIME_SCALAR, using 64-bit math

Few architectures combine the GIC with an external interrupt
controller. On such systems it may be necessary to update both
the GIC registers and the external controller's registers to control
IRQ behavior.
This can be addressed in couple of possible methods.
1. Export common GIC routines along with 'struct irq_chip gic_chip'
and allow architectures to have custom function by override.
2. Provide architecture specific function pointer hooks
within GIC library and leave platforms to add the necessary
code as part of these hooks.
First one might be non-intrusive but have few shortcomings like arch
needs to have there own custom gic library. Locks used should be
common since it caters to same IRQs etc. Maintenance point of view
also it leads to multiple file fixes.
The second probably is cleaner and portable. It ensures that all the
common GIC infrastructure is not touched and also provides archs to
address their specific issue.

PL310 implements the Clean & Invalidate by Way L2 cache maintenance
operation (offset 0x7FC). This operation runs in background so that
PL310 can handle normal accesses while it is in progress. Under very
rare circumstances, due to this erratum, write data can be lost when
PL310 treats a cacheable write transaction during a Clean & Invalidate
by Way operation.
Workaround:
Disable Write-Back and Cache Linefill (Debug Control Register)
Clean & Invalidate by Way (0x7FC)
Re-enable Write-Back and Cache Linefill (Debug Control Register)
This patch also removes any OMAP dependency on PL310 Errata's

WKUP domain
The parent of the interface clocks for GPTIMER1, MPU_WDT,
SYNCTIMER_32K, SCM, WDT1, and the ICR (2430 only) were all listed as
being l4_ck. This isn't accurate; these modules exist inside the WKUP
domain, and the interface clock to these modules runs at the SYS_CLK
rate rather than the CORE L4 rate.
So, create a new clock "wu_l4_ick", similar to the OMAP3
"wkup_l4_ick", that serves as the parent for these clocks.
Also, these clocks were listed as existing inside core_l4_clkdm;
wkup_clkdm is probably more accurate.
