Here are 2 patches against current mips-queue which add Au1300 and Db1300 devboard support. It's a work-in-progress, and has one serious flaw: I can't get the serial console to work reliably once kernel starts booting userpsace. Enabling debugging shows the enabling the proper irq, however hardly any interrupts arrive unless massive amounts of debug info (by way of the irq dispatcher) is dumped out to it. Once userspace has booted, and most debig output has been hidden (echo 0 0 0 0 > /proc/sys/kernel/printk) it continues to work as it should for a few bytes, then it dies. Judging from the debug logs it seems the UART generates far less interrupts than for example the au1200 ones. Until its figured out what's going on, please take the opportunity to have a look at the code and suggest better ways to implement things and bugs. Thanks!
