Help Adding new hardware support to AOSP

[Vadakattu Jagadeesh]

I am trying to add my new hardware(name is arya) to the existing AOSP ,but I was facing the Error,which is shown below

build/core/product_config.mk:222: *** Can not locate config makefile for product "arya". Stop.

** Don't have a product spec for: 'arya'
** Do you have the right repo manifest?

Yoy can also find the screenshot.

Hope for the solution


Thank You
