From cba4b1809f043bf85c806e5a4e342f62bd5ded45 Mon Sep 17 00:00:00 2001 From: Aneesh V Date: Tue, 16 Aug 2011 04:33:05 +0000 Subject: arm: do not force d-cache enable on all boards c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable() to board_init_r(). This enables d-cache for all ARM boards. As a result some of the arm boards that are not cache-ready are broken. Revert this change and allow platform code to take the decision on d-cache enabling. Also add some documentation for cache usage in ARM.
