Hi
After quick search I found (nearly?) identical SPI controller on many
other Loongson products. For example: ls1b, ls2k, 3A4000, etc...
Probably it will help you to make right decisions now, if you compare
this docs:

This does a lot of configuration, as far as I can see only
The SPI controller has the following characteristics:
- Full-duplex synchronous serial data transmission
- Support up to 4 variable length byte transmission
- Main mode support
- Mode failure generates an error flag and issues an interrupt request
- Double buffer receiver
- Serial clock with
3 matches
