# name. The two differ for u-boot-vybrid, which was published as u-boot-imx (an
# official fork of nxp-imx/uboot-imx). The mapping must stay explicit: the name
# github.com/EmcraftSystems/u-boot-vybrid is a stale redirect to the archived
# u-boot-fsl and would silently supply out-of-date sources.
# Repos not listed here are still fetched from GITURL (git.emcraft.com).
