From 88ebf5830fe25cfdfbbee726cb36ea71b111173a Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Tue, 23 Apr 2019 16:55:04 -0500 Subject: dm: cache: add the pl310 cache controller driver Add a PL310 cache controller driver that is usually found on ARMv7(32-bit) devices. The driver configures the cache settings that can be found in the device tree files. This initial revision only configures basic settings(data & instruction prefetch, shared-override, data & tag latency). I believe these are the settings that affect performance the most. Comprehensive settings can be done by the OS.
