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.
