From 520588f47f20a6dcaf81655e1da378e5fe6d5015 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 6 Jun 2007 17:58:56 +0900 Subject: [PATCH] sh: URAM node support for SH7722. This adds the URAM block on SH7722 as a separate node. Sparsemem is required for this, or it can simply be disabled by explicitly selecting a flatmem model.
