DMA implementation on MPC8572

Hi all I am using the MPC8572 processor. I wanted to use the DMA functionality in the powerpc board for talking to a FPGA device connected on the loacl bus. I have compiled the fsldma.c code and inserted it. On insertion the driver probes all the dma channels Can anyone tell me how to test the dr

external interrupt mapping with FPGA on loacl bus

Hi i have a FPGA called mcmc which is connected to the powerpc mpc8572 on the local bus. It provides 2 interrupts which are connected to the external interupts IRQ1 and IRQ3 of the mpc8572. the fpga is memory mapped on the local bus at address 0xc000 I am able to register the interrupt and obt

MPC85xx - accessing external interrupt

Hi all I am trying to use the external interrupts on the Powerpc architecture MPC8542 . My problem is that my driver is trying to request the external interrupt IRQ1, and I dont know what number use in INTR_NUM: request_irq(INTR_NUM, , , , ) As per the MPC85xx documentation Documentation/power
