I'm fine with this message, but more changes may be required for PE15
test, so I won't give r-b yet.

There is another patch for PE15, this one is needed for bug 3996.

As SBSA uefi tool can't configuare interrupt following
WatchdogTimerFlags in GTDT, and watchdog interrupt in Hi1620
is edge-trigger, so modify watchdog interrupt type for SBSA
test case 42.

The default link timeout value of USB 3.0 controller is a bit short
for some USB devices, and may cause it timeout in some cases.
We have modify the registers in IoInitDxe,but a bug let the modifying
not successful.

PE test case 15 flow:
Primary core(cacheable shareable) and slave cores(non-cacheable)
access the same memory area for communication.
For each slave core{
1 Turn on slave core;
2 run the payload function;
3 Write result in memory to notify primary core and follow
clean and invalid instruction;
4 Slave core turn off itself;
}
The result in DDR may rewrite by cache data. The essence of
this problem is that primary core and slave core access the
same area with different cache attribute.
Configure L3T register to fix this issue;

Does this change have any performance implications?
Prasanth: would PE test 15 not be _expected_ to fail if primary and
secondary cores access the buffers with different cachability
attributes?
