Juno R2: Configure the correct L2 RAM latency values
The default reset values for the L2 Data & Tag RAM latencies on the Cortex-A72 on Juno R2 are not suitable. This patch modifies the Juno platform reset handler to configure the right settings on Juno R2. Change-Id: I20953de7ba0619324a389e0b7bbf951b64057db8
