From dfbb9042801eaeb4df9015bb86224291a39a0f52 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 23 May 2007 17:48:36 +0900 Subject: sh: sparsemem support. This implements basic sparsemem support for SH. Presently this only uses static sparsemem, and we still permit explicit selection of flatmem. Those boards that want sparsemem can select it as usual.
