*	arm/raspberrypi: change interrupt dispatch and enable to generic vector id ↵	Pavel Pisa	2016-10-02	1	-43/+90

*	arm/raspberrypi: remove duplicate setup of IRQ handler in the main ARM ↵	Pavel Pisa	2016-10-02	1	-17/+0

For ARM architecture, it can be found in the file rtems/c/src/lib/libbsp/arm/shared/start/start.S and ends by bsp_vector_table_copy_done label. The actual tabel content can be found at bsp_start_vector_table_begin For ARMv7-A and even other variant with hypervisor mode support, it is even not necessary to copy table to address 0 at all because CP15 register can be used to specify alternative table start address arm_cp15_set_vector_base_address(&)bsp_start_vector_table_begin; ARMv7-M have register to set exception table base as well. Updates #2783
*	arm/raspberrypi: ensure that RTEMS application image can be started by U-boot.	Pavel Pisa	2016-10-02	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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. ldr r0, [r9, #GD_RELOCADDR] /* r0 = gd->relocaddr / mcr p15, 0, r0, c12, c0, 0 / Set VBAR */ Included changes in bsp_start_hook_0 restore default state to allow RTEMS image to run after startup from newer U-boot version on Raspberry Pi. Clear interrupt enable registers in interrupt controller to ensure that RTEMS starts from well defined state. Updates #2783
