This is not yet AMD announcing the licencing of ARM Cortex-A15, Cortex-A7, big.LITTLE, Mali-T658 and ARMv8, but it's a big deal for ARM and AMD to jointly announce two new major partnerships in one week.
Basically, ARM TrustZone (2) nears becoming the world standard to 100% safely replace online passwords and to securely authenticate everyone online. And ARM and AMD really want to make it easier for developers to use all chips on an SoC for attaining a maximum performance, thus enabling broad GPGPU compute etc.
