Run script automatically on startup.

Hi All,

I want to clear up some doubts related to the development using RZ/V2M Board eval kit v2.

1. How to open menuconfig and related settings to customize the application.
2. where can we find package manager to add/remove some packages?
3. File to run the script automatically and its procedure like in Beagalbone "Init.d"
4. How to enable HDMI?

Thanks in advance.
