For performance and multi-chip support, use dynamic layout instead of
statically configured pools.
Divide the shared memory into the 3 64-bit aligned layouts listed below:
vpu->param_addr -> +-----------------------------------------+
| |
| To SCP : Input frame parameters |
| (struct img_ipi_frameparam) |
| |
+-----------------------------------------+
vpu->work_addr -> +-----------------------------------------+
| |
| In SCP : Reserve for SCP calculation |
| |
+-----------------------------------------+
vpu->config_addr -> +-----------------------------------------+
| |
| From SCP : Output component config |
| (struct img_config) |
| |
+-----------------------------------------+
