commit 13e1b9f5219d48978c19372a63ef0da8b8321df0 Author: Aaron Durbin adurbin@chromium.org Date: Wed Feb 6 12:47:26 2013 -0600
rmodule: add 16 bytes of padding
There is a plan to utlize rmodules for loading ramstage as a relocatable module. However, the rmodule header may change. In order to provide some wiggle room for changing the contents of the rmodule header add some padding. This won't stop the need for coordinating properly between the romstage loader that may be in readonly flash and rmodule header fields. But it will provide for a way to make certain assumptions about alignment of the rmodule's program when the rmodule is compressed in the flash.
