MarsSeed [1] filed a deletion request for uboot-tools-rc [2]: Unmaintained release candidate package from 2020; it is 3+ years older than the stable release in extra repo.
As it has 0 votes or comments on AUR, I recommend deletion. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/uboot-tools-rc/
