[PATCH v2 0/8] dma-buf: heaps: Add secure heap

[Pavel Machek]

Hi!

> This patchset adds three secure heaps:
> 1) secure_mtk_cm: secure chunk memory for MediaTek SVP (Secure Video Path).
>    The buffer is reserved for the secure world after bootup and it is used
>    for vcodec's ES/working buffer;
> 2) secure_mtk_cma: secure CMA memory for MediaTek SVP. This buffer is
>    dynamically reserved for the secure world and will be got when we start
>    playing secure videos, Once the security video playing is complete, the
>    CMA will be released. This heap is used for the vcodec's frame buffer. 
> 3) secure_cma: Use the kerne CMA ops as the allocation ops. 
>    currently it is a draft version for Vijay and Jaskaran.

Is there high-level description of what the security goals here are,
somewhere?
