Patches required to boot by U-boot
* bsps/arm: CP15 support for flush prefetch buffer and table base control.
* arm/raspberrypi: ensure that RTEMS application image can be started by
U-boot.
Correction of weirdness
* arm/raspberrypi: correct GPIO pin function selection.
*

This is required if function or direction is changed by some driver
after start of thread multitasking or in interrupts drivers.
There can be problem with calling GPIO function selection before
data section is initialized. But actual ticket lock implementation
seems to be compat

The current versions of U-boot start kernel/RTEMS application image
with instruction and data caches enabled and it sets exception
base register to new address after its self-relocation.

From: Pavel Pisa
Original implementation does only bitwise-or with previous register
value for all functions except IN. Switch from one to other function
would lead to incorrect value.

If the raspberrypi.h has been included without preceding inclussion
of bsp.h then BSP_IS_RPI2 has not been set for Raspberry Pi 2
BSP variant and bad things happen later.
The patch includes bspopts.h by raspberrypi.h and even includes
bsp.h in critical peripherals support.
