My recollection would indicate these peripherals are not on the 162 board. These never should have been merged into the rtems source tree and modifying confdefs.h to get them is not riht unless you are proposing standard ways for everyone to follow.
Build the drivers in your application space somehow and add them with the confdefs.h parameter which is named something like CONFIGURE_EXTRA_APPLICATION_DRIVERS.
