The CPUACTLR_EL1 register on Cortex-A57 CPUs supports a bit to enable non-cacheable streaming enhancement. Platforms can set this bit only if their memory system meets the requirement that cache line fill requests from the Cortex-A57 processor are atomic. This patch adds support to enable higher performance non-cacheable load forwarding for such platforms. Platforms must enable this support by setting the 'A57_ENABLE_NONCACHEABLE_LOAD_FWD' flag from their makefiles. This flag is disabled by default.
