The RegisterResetNotify() function registers a notification function that is called when

ResetSystem()is called and prior to completing the reset of the platform.

The registered functions must not perform a platform reset themselves. These

notifications are intended only for the notification of components which may need some
|
|
special-purpose maintenance prior to the platform resetting.
|

The list of registered reset notification functions are processed if ResetSystem()is called
|
|
before ExitBootServices(). The list of registered reset notification functions is ignored if
|
|
ResetSystem()is called after ExitBootServices().
