[ptxdist] Modifing platform rules

Hi,
I'm trying to get use the kernel from an external source (git repository).
The chapter 6.1. defines this how to do this, however it doesn't suite me because it requires additional manual work for someone setting up the build system.

I know how to write the .make and .in file for the kernel but in the userpace configuration (creating kernel.in and kernel.make in /rules) but that would completely ignore the kernel platform settings which I don't believe is the intended way.

What is the proper way to extend the platform rules and .in files?

Do it in the platform. But the folder names differ. The *.make files should be 
still in the rules/ directory inside the platform directory, but the 
corresponding *.in file must be located in the platforms/ directory.

So, if your platform is located in configs/platform-myboard/ the kernel rules 
must be located in:

configs/platform-myboard/platforms/kernel.in
configs/platform-myboard/rules/kernel.make

Happy hacking

Hi,

I'm trying to add a new menu option in the platform Kconfig.

Here is what i did so far:
Copy the /usr/local/lib/ptxdist-2014.09.0/platforms/Kconfig to oselas.bsp/platforms

I've tested it and changes on the oselas.bsp/platforms/Kconfig are shown in the platformconfig.
I want to add a new top level menu entry.
I add:

menu "custom image creation rules  "
source "platforms/custom_image.in"
endmenu

to oselas.bsp/platforms/Kconfig and that
gives a "can't open file" when running ptxdist platformconfig

However, if I put an absolute path, everything works.

menu "custom image creation rules  "
source "absolute_path_to/platforms/custom_image.in"
endmenu


Relative to what path does the extended Kconfig look for .in files?
