Subject: [Patch] BaseTools: Add DevicePath support for PCD values
Date: Thu, 28 Dec 2017 10:18:05 +0800 [thread overview]
Message-ID: <1514427485-4112-1-git-send-email-yonghong.zhu@intel.com> (raw)
Use C code parse device path to output hex string, and Python
run command when PCD Value need device path parse.
