I basically agree with manu@, but there could be few points we may have to consider: - It is nice to have the support of a board which has SATA controller, as mentioned Rogiel - According to https://wiki.freebsd.org/FreeBSD/arm/Allwinner most of drivers work on A20 boards (if we add ccung support) and it could be a reference code for attracting new developers, users etc. - If we nuke A10/A20 bits, then we maybe need to obtain some other boards with H3 SoC for gjb@ or anyone who builds official images, I believe those images are tested on those boards. - I know it is time consuming, but I think a developer has to make sure his/her code changes work across boards/SoC family, or at least ask others to test or apply similar changes to their boards/SoCs just to make sure everything works. Correct me if I'm wrong here. - I know I should be blamed for not updating Rockchip RK3188 and Amlogic codes, but I hope some of the bits can be used/referenced later on for boards with SoC like RK3328, RK3399 etc, since I do have the latter one. Kyle, Adding ccung support to A10/A20 is very much appreciated. I will wait for your switch driver, that would be really awesome. I think I have same board too :) thanks a lot for understanding, Ganbold > > Thanks, > > Kyle Evans > _______________________________________________ > freebsd-arm@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-arm > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org" >
