the interruption port of the mhs file:
PORT Intr = ethernet_interrupt & debug_uart_interrupt & 
console_uart_interrupt & timer_interrput

reading the csr register of the timer after the time of a tick returns 
me the value of 0x1d0, the bit 23 is set to "1", an interrupt has occured.

I wasn't able to find witch interrupt function is called, in 
linux-2.4.x/arch/microblaze/kernel/irq.c, I put a printk in the begining 
of every function.

Thanks,
Didier
