I'm replying to this because I'd like some confirmation on the development process. u-boot is an open source bootloader. It isn't run by a single organization (though it IS headed by denx). Architecturally the software can be divided into multiple processor and development boards. Now, if organization A is developing a new processor (along with development board) and they want to use u-boot as the bootloader, they would need to write the necessary /cpu sections by themselves and post it as a patch to the u-boot mailing list. Assuming it meets the coding standards, it will usually get accepted. After that, organization A would need to develop the necessary board additions and submit that as a patch as well. Why are things done this way? From the mailing list perspective, it is organization-A which wants to port u-boot to their brand new processor/development board. Thus, organization-A will need to do the hard work to make it happen. organization-A is, of course, free to ask for help or assistance from the mailing list and is encouraged to use the architecture independent modules (part of u-boot) in their development. Looking it at from another perspective, it is rather arrogant (and rude) of organization-A to build a brand new processor, come in here and expect u-boot to magically support it. Most people don't work for free. And even if they wanted to, since the rest of the mailing list does not have physical access to the new processor/board, how much help can you _reasonably_ expect? > > Nvidia has decleared 64bit SOC plan. > > So, i think bootloader for ARMv8 SOC is urgent now. Coming back to your specific case, I would think it best to ask nVidia if they have any plans to support u-boot on the new ARMv8 SOC. Can someone more experienced from the list confirm/deny my understanding? -Abraham V. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
