Can you give me link to the "ERRATA ERR005829 (A-008965)" description?
The errata ERR005829 is described here
http://cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf and it's
fixed by mainline commit:
25e924450fcb can: flexcan: implement workaround for errata ERR005829
Is your "ERRATA ERR005829 (A-008965)" something different?
> Errata handling via Kconfig seems pretty common in the kernel (see [1])
Yes, for the ARM Core itself.
