The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is claimed for Cortex-A9 (r1p0..r2p2). Though i.MX6 uses a newer revision than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be fixed by applying the workaround for this errata. So for safety, let's define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6.

This is a fix, but the release is coming (end of the week). What do you think if I push this to -next ?

Best regards, Stefano
