I believe there is some misunderstanding, we do not license the Mali drivers per board. We license our GPU designs to other companies, who then design the part into their products and SoC's. They pay us an up-front licence fee, as well as royalties on all parts produced. As part of the license agreement we provide them with the Mali Driver Development Kit (DDK) which enables them to build drivers which they would then provide to their end users. Are you creating your own SoC, or are you producing boards using an existing SoC containing a Mali GPU? In the latter case, you can approach your vendor who ought to be able to provide you with the runtime libraries necessary to use the Mali GPU.
