What tools are you referring to?
There are two tools.
1. sopc-create-header-files
It is included in altera design suite v8.0 or later. I used this in the initial version of nios2-generic board.
2. sopc-create-config-files
The script is available at
http://sopc.et.ntust.edu.tw/?p=toolchain-build.git; a=blob_plain;f=tools/sopc-create-config-files;hb=HEAD
I wrote this to generate unified u-boot header files, while I was discussing with Michal Simek. He liked this approach and I got his Acked-by of this patch.
Support for several Altera nios2 boards has been available in u-boot for at least four years. To date, this vendor has offered no support whatsoever, either through patches, files, consultation or otherwise.
Is there any reason you believe this is likely to change?
We really appreciate your work. But these boards are getting obsolete, and there are more new boards unsupported. We cannot add every board, and a generic approach should be taken as Michal suggested. We, (you, I , the community and Altera), should work together to offer a better solution.
The binary generated with the nios2-generic target should work on these three boards. I tested on EP1C20 and I believe it will work on the other two. These boards are still supported, just under a different name.
no need to include other boards support for nios2 in the u-boot mainline.
I'm not convinced that this is true.
Michal's work on microblaze-generic already proved this.
