* include/pkgconf/mlt_arm_lpc24xx_ea2468_rom.ldi:
* include/pkgconf/mlt_arm_lpc24xx_ea2468_ram.ldi: Relocate fixed vectors to 0x40000020. Previously, the HAL_VSR_GET/SET macros accessed the wrong locations and didn't have any effect; now both hardware and software have the same idea of where the VSR table is. NOTE: that this renders RAM applications built with this layout incompatible with RedBoot built with the old layout. A new RedBoot needs to be installed. * cdl/hal_arm_lpc24xx_ea2468.cdl: * tests/fiq.c: Add FIQ test program.
