How to find BOOTSEL pins location

I'm having a hard time looking for HPS special pins for board design. Pins like BSEL and CSEL does not appear in the .pin file, also are not marked as special pins in the Pin Planner.

How am I supposed to find out their position for a particular device?

I've tried to find them in Pin Planner but as far as I know there's no search which would match pins description (unfortunately, it's definitely not the first time it would be useful).

I'm using these docs https://www.altera.com/support/literature/lit-dp.html (https://webmail.macnica.com/owa/redir.aspx?surl=ut0gy0undpvypll49iltpe4fb24_3atay-krg-n-joywpl_jal_scggadab0ahaacwa6ac8alwb3ahcadwauageabab0aguacgbhac4aywbvag0alwbzahuacabwag8acgb0ac8ababpahqazqbyageadab1ahiazqavagwaaqb0ac0azabwac4aaab0ag0abaa.&url=https%3a%2f%2fwww.altera.com%2fsupport%2fliterature%2flit-dp.html) but it's not really friendly.

Is there any better way to find BSEL physical pin location?

Thanks!
