Hi Kever,

That is true but at least here at Poland there are still rk3066 devices which you can buy. And i don't think it's an exception. There are known cases in opensource community of support for hardware much older than 10 years. I.e. thanks to Linus Torwalds linux still supports EISA FDDI [1]. There are at least a few rk3066a SOC users and in the spirit of Linus Torvalds' open source principles, adding support for this platform is the correct step. RK3066 is a great soc to play with. I use my MK808 for three years now to keep my 3d printer in contact with my local network. I have been using the URZ0350 as a wifi camera for a long time. And guess what! They don't want to break down.

I do not agree. As long as the world is using armv7 architecture adding support for SOC rk3066a is a great and noble idea. I personally am working on following up on my and Johan's patches by adding support for writing firmware to these devices, using only opensource tools like u-boot and rkflashtool. This support can be extended to other devices such as rk3399, rk3568 and others. So other SOCs can also benefit from adding support for rk3066a. I also want to add that Linux actively supports rk3066a [2]. So if linux supports it, U-BOOT SHOULD ALSO! [2] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/?qt=grep&q=rk3066 I appeal to you Kever Yang in the spirit of opensource, don't give up on rk3066a yet. These devices are there and they work!
