Applied to u-boot/next, thanks! -- Tom signature.asc Description: PGP signature

AFAIK a login (free of charge, besides registering the e-mail address) is required to download NXP documents. This way you always get the latest document version, not a old version from some archive. Maybe Fabio knows a better way how to reference NXP manuals? Otherwise for this u-boot board documentation the link from linux would be fine with me, maybe with the additional archive reference.

Archive.org/web has many links for that page, but I only found one of them to work, which is older than the archive of the link I had: https://web.archive.org/web/20180829173128/https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf I'm not aware of any project tracking datasheet / reference manual URLs and versions though, but it would probably be something very useful to have. At some point, I plan to see if it's possible to something like that with Wikidata, but I'm not sure if it's fit to track datasheets URLs over time.
