The size of reserved HwErr variable space. Note that this value must be less than (PcdFlashNvStorageVariableSize - EFI_FIRMWARE_VOLUME_HEADER.HeaderLength - sizeof (
VARIABLE_STORE_HEADER)).
In EdkII implementation, HwErr type variable is stored with common non-volatile variables in the same NV region.
so the platform integrator should ensure this value is less than (PcdFlashNvStorageVariableSize - EFI_FIRMWARE_VOLUME_HEADER.HeaderLength - sizeof (
VARIABLE_STORE_HEADER)).
this value is used to guarantee the space of HwErr type variable and not populated by common variable.
HwErr variable storage size.
