Hi Kevin, Shuge, I think it is great that Allwinner wants to get more involved in upstream sunxi support. As one of the 2 custodians (maintainers) for the upstream u-boot support for sunxi devices, I would like to ask Allwinner to also get more involved in upstream u-boot support. Ideally Allwinner would switch to using upstream u-boot entirely, including using a standard u-boot SPL, rather then chainloading an older u-boot fork through boot0 and boot1. I can understand that completely switching to upstream u-boot will take time, and that you may need some additional features in upstream u-boot before you can switch. In the mean time it would be great if you could help us extend the existing sunxi support in upstream u-boot. Currently we support sun4i, sun5i and sun7i. We would love to also support sun6i and sun8i (and the A80). We already have some limited sun6i and sun8i support in the linux-sunxi u-boot-sunxi git repository. The biggest stumbling block keeping us from adding support for sun6i and sun8i is the lack of code to initialize the DRAM controller. It would be a big help for us if you could share the boot0 code for sun6i and sun8i with us, either under an open license, or with an explicit permission notice for copy and pasting parts of that code and releasing the result under a GPLv2+ license. If you've any questions about or suggestions for upstream sunxi u-boot support please send a mail to me and Ian Campbell (the other sunxi custodian, whom I've added to the CC). Regards, Hans p.s. Note that even though I'm using my company's email address for this, that I do my sunxi u-boot / Linux work on a personal title. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
