My processor is Mpc8306. And my code must run in Uboot., not in linux. But I can not find any handbook to describe wirte interrupt function. I download gcc manual. The manual does not say about gramma about ppc interrupt. For example, gcc book describe the ARM interrupt: "void f () __attribute__ ((interrupt ("IRQ")));" , it is a interrupt handle function to tell gcc compile. Also, I don't know how to write assemble like start.s in uboot, The start's file has something like "GOT_ENTRY(_FIXUP_TABLE_)", I don't know what it mean.
Please help me?
