From 877c0a93be4317f5715347359cc78d41f4654748 Mon Sep 17 00:00:00 2001 From: Yonghong Zhu Date: Wed, 23 Mar 2016 17:55:50 +0800 Subject: BaseTools: generate alignment when the FV content come from the filesystem when the FV contents come from the filesystem instead of from a named FDF section, the build tool missed to generate alignment for this FV. The fix is get the alignment value from FV header and use this value to generate alignment.
