[U-Boot-Users] install_hdlr usage for interrupt handling

Hi list, I want an interrupt aware application running on u-boot.I found that install_hdlr() is available in the u-boot api. But jumptable_init() in common/exports.c has install _hdlr going in only for i386 and ppc.. am I missing something here?? Also,what would be the best way to install an interrupt handler?? I am on a custom blackfin 532 based board. TIA -- P
