Hi All!
For several years, my organization has built and maintained boards SPARCH-architecture processors (specifically Gaisler's implementation of the LEON3), and we have depended on u-boot as our primary bootloader. But when attempting to update u-boot this morning, we were disappointed to find that the SPARC support was completely removed last March with commits:
936478e797a87bcd4e002bf70430b6f58584b155

What was the reasoning for completely removing support for SPARC? What will it take to get it back in?
It was removed due to a lack of active maintainers. Last year when I removed it, I know a few people reached out to other groups in private to see if anyone wanted to maintain it, and no one stood up. I would be happy to have SPARC re-introduced, so long as: - It builds with a modern toolchain such as https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/6.4.0/ or https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/7.3.0/ - It does not add anything to scripts/config_whitelist.txt - Someone is going to be active in maintaining the port and doing the driver conversions to DM as they need to be done. - A real nice bonus would be hooking up QEMU and Travis-CI and test.py so that a basic level of functionality can be confirmed and tested every time.
Thanks!
