From 83571bcab10bc8d6d73dc77b64442dbd281afc99 Mon Sep 17 00:00:00 2001 From: York Sun Date: Wed, 26 Feb 2014 13:26:03 -0800 Subject: armv8/cache: Flush D-cache, invalidate I-cache for relocation If D-cache is enabled, we need to flush it, and invalidate i-cache before jumping to the new location. This should be done right after relocation.
