[U-Boot] [Question about ppc4xx]
Hello there..
I'm working on my custum board based on SEQUOIA.
I'd like to use SPI & IIC in my linux application.
Where should I start??
Do I have to make my own driver to read & write via SPI & IIC??
Or, are there any usefull drivers in the kernel or somewhere??
If it is, how can I use them?
If you have sample code, would you give me them??
Best regards

I can tell you where *NOT* to start: on a mailing list like the U-Boot list where your request is off topic.
Best regards,

First this is the wrong mailing list then. Its about U-Boot questions and you are asking about Linux I2C and SPI support. I suggest you move this over to linuxppc-dev.

To give you a quick answer to your questions: I2C is supported for 4xx in the current Linux kernel. SPI is still missing but I'm currently busy with integrating the 4xx SPI support and pushing it upstream. In a few days/weeks you should see something on the lists.
