[U-Boot] U-Boot Boot Count Limit

Hello,

does U-Boot support the Boot Count Limit functionality for a MPC5200?

My last information was that is only supported for MPC8xxx and MPC82xx PPC.


TIA

Axel

AFAIK no.

Not quite, e.g. a quick grep turns up support for mpc8260, 4xx, ixp,
... but not for MPC5200. Implementing it should not be very diffcult
though, I would assume.

Yes, use the "breadcrumb register" and I'm serious about that (chapter
5-14) ;)
