Hello,
I have added interrupt support for armv7 platform, by implementing the do_irq and irq_install_handler and arch_interrupt_init functions.
Initially default_isr is the handler function installed for all the interrupts.
From my standalone application, I am enabling the interrupts and installing
the handler to be called for my peripheral interrupt.
If I don't install my handler, U-Boot executes default_isr successfully.
If I use my handler, when the interrupt occurs I am getting the prefetch abort exception with the following dump prefetch abort pc : [<ebd78002>] lr : [<bff8f720>] sp : bfeef200 ip : bfeef358 fp : bfef1d48 r10: bfef1d78 r9 : 00000002 r8 : bfeeff58 r7 : bffac284 r6 : 60000153 r5 : bffbb5c0 r4 : 00000000 r3 : bffab29c r2 : 00000000 r1 : 000003e8 r0 : 8500178c Flags: nZCv IRQs off FIQs off Mode IRQ_32 Resetting CPU ...

Can any one please help me to solve this?
