From 42e6856436e6ee1f9b8ae1039ac5a0921e001377 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 9 Jun 2015 13:55:51 -0500 Subject: stage_cache: use cbmem init hooks Instead of having the chipset code make the approrpiate calls at the appropriate places use the cbmem init hooks to take the appropriate action. That way no chipset code needs to be changed in order to support the external stage cache.
