|

*
|

* When the start and end addresses have crossed two different sections, we

* need to break the L2 operation into two, each within its own section.
|

* For example, if we need to invalidate addresses starts at 0xBFFF0000 and

|

* Note 1:

* By breaking a single L2 operation into two, we may potentially suffer some
|

* performance hit, but keep in mind the cross section case is very rare
|

*
|

* Note 2:
|

* We do not need to handle the case when the start address is in

* Section 1 and the end address is in Section 3, since it is not a valid use
|

|

*
|

* Section 1 in practical terms can no longer be used on rev A2. Because of
