From fa840676f5f3bd92b63c352f0c8bf6f14bc2c314 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Wed, 9 Apr 2014 21:07:43 -0500 Subject: ec/compal/ene932: Update to use coreboot EC-mainboard API This patch implements a simple interface between the EC and mainboard ASL code. This interface does not rely on the preprocessor, and prevents name conflicts by scoping the interface methods. As this interface is documented on the coreboot wiki, an in-tree documentation is not provided.
