TDA2PXEVM: How do we make sure the early boot is normal

Hello，

Refer to VisionSDK_Linux_UserGuide,and applied the patch of early boot, and we had debuged to make system boot normal.But we are not sure that how to make sure the early boot and late attach is normal, are there any other documents for reference?

 Find the boot log in below, please. Could you help us to make sure the boot log is normal?
