An updated variant of the older patch http://lists.denx.de/pipermail/u-boot/2015-February/204024.html
These patches are not for the u-boot code (unless u-boot decides to cannibalize the 'fel' tool later) but still provide a glue layer between the Allwinner BROM code and the u-boot SPL code. And need to play nice with both of them.
It's an interesting idea actually - I wonder what people think about putting these tools in the source tree. I suspect it could get a bit out of hand? But it would make it easier to keep things in sync,
Yes, keeping it is sync with the mksunxiboot program would be easier in this case.
But I searched a bit, and can see that sunxi-tools is already packaged in some linux distributions, for example:
https://packages.debian.org/search?keywords=sunxi-tools
Maybe it's better to keep the 'fel' tool in the 'sunxi-tools' package and just make sure that it gets reasonably well supported in linux distributions.
In addition, there might be other bootloaders or "bare metal" users. I have found this very cool project, which relies on the FEL mode and allows to run code on the OpenRISC core in Allwinner A31:

What's particularly interesting is that it apparently had the DRAM controller support for A31 (sun6i) even before this was implemented in u-boot :)
