Subject: [PATCH 4/5] ARM: mvebu: Enable SCU Speculative linefills to L2 for Armada 375/38x

From: Nadav Haklai <nadavh@...vell.com>

For Armada 375 and Armada 38x SoCs, enable the SCU Speculative
linefills.

This feature may improve overall system performance.

[Gregory: modify the title of the patch and no more copy the defintion
of the bit here]

[Gregory: use the new function scu_spec_linefills_enable instead of
implementing SCU specific feature at board level]
