There are three problems: 1) A lot of U-Boot images are already very close to the 512KB limit. We often have to disable features in U-Boot to get it to build properly. An additional 64KB would be prohibitive. 2) The firmware license is not exactly GPL-compatible. The firmware files themselves are freely distributable, but the source code is closed. I'm not sure how that would work in a GPL U-Boot. 3) For Fman, at least, we often update the firmware after the board ships, which means you would need to update U-Boot to get a new firmware. So no one might actually use this feature because they're afraid they won't be able to update the firmware. If you can do it, go ahead. I would approve a patch that adds the ability to inject a firmware binary into u-boot.bin, provided it's controlled via a build or CONFIG_SYS_xxx option. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
