1. add Include folder which contain the *.h file which used by Tiano tools.
2. Change ${evn.WORKSPACE}/MdePkg to ${PACKAGE_DIR} in build.xml.

The device path protocol as defined in EFI 1.0.
|
|
|
|
The device path represents a programatic path to a device. It's the view
|
|
from a software point of view. It also must persist from boot to boot, so
|
|
it can not contain things like PCI bus numbers that change from boot to boot.
