* Description:
* ------------
* This fie is created to solve HAL High issue on 11BW11.44MP.
*
* This file is a wrapper of driver layer global variables and should be maintained
* be the related driver owner because it's bad design that low layer to extern global variable to
* upper layer, low layer should provide this wrapper interface, the context of these global variable
* is also maintained and only can be modified by the related driver layer owner who has the
* domain knowleage wholly.
*
* But due to history reasion and a bad design when it born, Driver owner don't want to
* take it back to home even after great discussion, but we have to solve the 4N HAL high
* issue and have to create this file, and just let it dead in the long time in the future.
*
* This file it not belongs to the creater but really created by the creater, so announce here:
* NO ONE IS ALLOW TO MODIFY IT UNLESS YOU WANT TO BE THE OWNER OF THIS FILE.
