Hi, Consider a simple driver which needs that some data structures be filled by the Platform, which is using the driver.
Driver.c #include <Platform.h> Struct a = platformVal; We can define platformVal in Platform.h, which would be unique to the platform being built. This Platform.h can be placed in include directories, whose path would be defined in Platform.dec file. Now, whenever we build driver for each unique platform, we need not to mention Platform.dec file in driver.inf [packages] section. We can append Platform.dec include paths to each driver. i.e. look for the include files in [packages] section as well as in Platform include directories. For this, I am looking for Platform.dec file in same directory as Platform.dsc and using same name as Platform.dsc We can refine this change further. i.e. add Platform include directories to driver's include paths based on some condition in driver.inf file.
