I had a quick try on one of the kirkwood based boards I have. It was pretty easy to bring in the dts files from Linux and get some basic stuff working. I started with i2c since I can still boot without it, I haven't been brave enough to try spi yet. Hopefully I can spend a bit more time on it over the weekend. In terms of a long-term plan. I could upstream support for our board, we still include it in the source we distribute as part of our GPL compliance. Since it's a older board that has been fairly stable we're not doing a lot of development on it. My motivation for retaining support for kirkwood is just in case we have some other EOL part that requires us to release a new bootloader. I could do a blind conversion of other in-tree kirkwood boards but my ability to test them would be quite limited. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
