I think you need to be really careful about statements like this. As you know, it is possible to run a 32bit environment in a VM on the 64bit CPUs. So, its entirely possible to run a 32bit setup on a Cortex A72 for example, and that means such a setup _is_ vulnerable to variant 3a. Do people do this? That isn't something we can really know, but I think as long as its allowed, you can bet that someone will, and someone will end up using it in a production environment. So, it can't be ignored. -- Russell King _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
