Macros
#define	BSP_SHARED_HANDLER_SUPPORT   1
	Include some preprocessor value also used by assember code.
#define	BSP_IRQ_VECTOR_BASE   BSP_ASM_IRQ_VECTOR_BASE
	Base vector for our IRQ handlers.
#define	BSP_IRQ_LINES_NUMBER   16
#define	BSP_IRQ_MAX_ON_i8259A   (BSP_IRQ_LINES_NUMBER - 1)
#define	BSP_IRQ_VECTOR_NUMBER   17
#define	BSP_IRQ_VECTOR_LOWEST_OFFSET   0
#define	BSP_IRQ_VECTOR_MAX_OFFSET   (BSP_IRQ_VECTOR_NUMBER - 1)
#define	BSP_PERIODIC_TIMER   0
	Interrupt offset in comparison to BSP_ASM_IRQ_VECTOR_BASE NB : 1) Interrupt vector number in IDT = offset + BSP_ASM_IRQ_VECTOR_BASE 2) The same name should be defined on all architecture so that handler connection can be unchanged.
#define	BSP_KEYBOARD   1
#define	BSP_UART_COM2_IRQ   3
#define	BSP_UART_COM1_IRQ   4
#define	BSP_UART_COM3_IRQ   5
#define	BSP_UART_COM4_IRQ   6
#define	BSP_RT_TIMER1   8
#define	BSP_RT_TIMER3   10
#define	BSP_SMP_IPI   16
#define	BSP_INTERRUPT_VECTOR_COUNT   BSP_IRQ_VECTOR_NUMBER

Typedefs
typedef unsigned short	rtems_i8259_masks
	Type definition for RTEMS managed interrupts.
