Hi Thomas, Thomas Chou wrote: The example configuration files of nios2-generic board can generated binary to run on the EP1C20, EP1S10, and EP1S40 boards. So the three boards can be removed. With nios2-generic approach, the fpga parameter header file can be generated from hardware designs using tools. Porting u-boot for What tools are you referring to? nios2 boards is simplified. Vendors can supply their fpga parameter file or patches to add a new nios2-generic board instance. There is 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? no need to include other boards support for nios2 in the u-boot mainline. I'm not convinced that this is true.

Porting u-boot for 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. Best regards, Thomas ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

GPL ... very nice! This addresses several of my big concerns. 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. Agreed. And please realize that I think the generic approach is a great way to proceed. I listed my concerns in an earlier response to Dalon. The availability of your GPL-ed script addresses most of them. 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. I tested on the 1c20 this evening as well ... works fine. I will test on the 2c35 board tomorrow.

I'm not convinced that this is true. Michal's work on microblaze-generic already proved this. Michal proved the concept ... and the microblaze implementation (many thanks for your contributions Michal). I'd like to _know_ that nothing is broken before we remove existing code -- I don't want to leave anyone high and dry. I've been in such situations ... it's no fun. I'll apply the generic board patch to the nios 'next' branch, but I'd like to hold off on blowing away those other board trees until we get a chance to test the generic board on the actual targets. Fair enough? Thanks for your efforts. Regards, --Scott ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
