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?
BR,
Pavel
