Thanks Timothy for quick response !!

Another basic question, mainly to understand..
So, I understand that kernel/initramfs integrity is important, and 
signing is required, but what drives the need for encrypted 
kernel/initramfs.

What confidential information is possible via vmlinux ?

Thanks & Regards,
