E.g. what I did for OMAP3 SPI driver:

Hi Dirk,
I could not find this code in any of the repositories. Could you share the u-boot omap3 spi driver?
I used the SPI driver for DaVinci (which this thread is about) as starting point for an U-Boot OMAP3 driver. The goal was to be able to access SPI ethernet on Zippy expansion board for Beagle. Unfortunately, I never found the time to finalize it.
Please find my latest patch from beginning of January 2010 in attachment.
I really hope it might help to finalize it!
Many thanks for asking and best regards
Dirk
P.S.: You might notice that the patch contains changes for the SPI ethernet, too. This should be moved to a separate patch.
