From 0424c95a6dafdb65070538d6c5aa394b75eb9850 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Sat, 28 Mar 2015 23:56:22 -0500 Subject: fmap: new API using region_device Instead of being pointer based use the region infrastrucutre. Additionally, this removes the need for arch-specific compilation paths. The users of the new API can use the region APIs to memory map or read the region provided by the new fmap API.
