AVR32 PATA driver
Updated and simplified driver. Use only register transfer timing for both data and register transfers. This gives poorer performance in PIO1 and 2, but should not be a problem in PIO3 and 4, correct me if I'm wrong :) The driver works very we'll but I still wonder about the interrupts. I have an interrupt line, that works nicely when POLLING flag is not set. The problem is the number of interrupts that eat away my CPU cycles. When using the POLLING flag there seem to be some interrupts that dosen't get cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts and generates a lot of interrupts due to ripple / noise. What to do?
