contents of the restricted access region control
registers.
The restricted access region control registers
(rar_registers) are used to pass address and
locking information on restricted access regions
to other drivers that use restricted access regions
The restricted access regions are regions of memory
on the Intel MID Platform that are not accessible to
the x86 processor, but are accessible to dedicated
processors on board peripheral devices.
The purpose of the restricted access regions is to
protect sensitive data from compromise by unauthorized
programs running on the x86 processor.
