Mainly for others, the BSP default cleanup operations
selection mechanism is defined in
rtems/c/src/aclocal/bsp-bspcleanup-options.m4
RTEMS_BSP_CLEANUP_OPTIONS
dnl USAGE:
dnl RTEMS_BSP_CLEANUP_OPTIONS([0|1], [0|1], [0|1])
dnl WHERE:
dnl argument 1 indicates the default value for BSP_PRESS_KEY_FOR_RESET
dnl argument 2 indicates the default value for BSP_RESET_BOARD_AT_EXIT
dnl argument 3 indicates the default value for BSP_PRINT_EXCEPTION_CONTEXT
To change Raspberry Pi behavior it should work to specify
../../rtems/configure --target=arm-rtems4.12 --enable-rtemsbsp="raspberrypi2"
... \
BSP_RESET_BOARD_AT_EXIT=1
The default for RPi2 can be changed by
diff --git a/c/src/lib/libbsp/arm/raspberrypi/configure.ac
b/c/src/lib/libbsp/arm/raspberrypi/configure.ac

Actual implementation reboots the board and firmware starts again to load
application. I can add variant which ends with something like power
down after firmware restart. Actual operation is equivalent to Linux "reboot",
I can change that to (add variant) equivalent Linux "halt".
Best wishes,
Pavel
