Is this a completely new BSP?

For ARM9 based systems you only need to provide the low-level interrupt
controller code.  Please have a look at the lpc24xx BSP (irq.h and irq.c).

http://www.rtems.org/onlinedocs/doxygen/cpukit/html/group__rtems__interrupt__extension.html

You may have a look at (with Doxygen comments):

c/src/lib/libbsp/shared/include/irq-config.h
c/src/lib/libbsp/shared/include/irq-generic.h
c/src/lib/libbsp/shared/src/irq-generic.c
c/src/lib/libbsp/shared/src/irq-legacy.c
