Apart that I agree that such as work-around should be applied just to the affected SOCs, which is the issues to apply them to the whole MX6 family ? For example, 751472 requires to set CP15 bit 11 with a specific sequence. Right, single core MX6 do not need it, but even if this is set in this way, is there a side-effect ?
