If the core runs at higher than x3 speed of the platform, there is
possiblity about sev instruction to getting missed by other cores.
This is because of SoC Run Control block may not able to sample
the EVENTI(Sev) signals.
Configure Run Control and EPU to periodically send out EVENTI signals to
wake up A57 cores.

Why do you need a variable to override the calculation?

Please add a comment here to explain what the interval does and why it is
calculated this way.

Following needs to be supported as part of errata workaround
1. Ability to modify platform clock value to increase time interval
2. Disable workaround in platform clock 0
As per Errata workaround,
"For <interval> value above, it is the number of platform cycles between wake up events generated by EPU. For example:
A typical value is 1 microsecond. If the platform frequency is 500MHz, each cycle is 2ns. interval = 1us/2ns=500=0x1F4."

This is taken care of by the formula. Is there any need to adjust the time
interval? If you do, you are risking of running too fast or too slow. If setting
the variable as 0, does it have the same effect as not running this workaround?
If this is a debug technique, please remove if not required by the workaround.
If you really want to support override, please add a comment inline and in
commit message.

Yes, customer may like to increase or decrease the time interval to fine tune the system behavior.

Yes, setting 0 == Not running WA. I verified it.

This problem occur when core clock is > 2.5.x of platform clock.
