I just noticed this mail today, sorry for the late reply. Thanks Henrik for introducing this in the u-boot mail list.
I am Tom Cubie, a former engineer at Allwinner. Allwinner Tech is a 5-years-old Chinese company making low cost ARM soc.
I joined Allwinner last year, and have been working on the Linux BSP, U-boot and some device drivers. To help speed up development and improve resource usage i suggested that we Allwinner should open source and work with the open source community as it is the fastest way for Allwinner engineer to learn and get feedback. At that time the EOMA project announced that they will make computer-on-module using allwinner A10 chip. I have been trying to advocate the benefits of open source within the company since then.
The community's work are based on a number of source releases by both Allwinner and their customers. Though there are source code public. i feel that there are not many developers (like Henrik) on Allwinner platform.
I think one reason is no good hardware to work on it and also the lack of documents. So my colleagues and i, we made the cubieboard (cubieboard.org), a low cost board based on A10. Hope that we can improve the FOSS on Allwinner platform. Because of family reasons I recently quit my job at Allwinner and decide to run cubieboard project fulltime while still get support from my former colleagues. If there are developers in the mail list interested in hacking the board, welcome. We offer special orders to developers.
