[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

Dear =?ks_c_5601-1987?B?sei/tbz4?=,

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,

SW engineering is a race between programmers trying  to  make  better
idiot-proof programs and the universe producing greater idiots.

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.

Best regards,
Stefan
