FLow add a new IP

[nguyendaithien]

First of all, I would like to thank you for creating these tutorials. My problem is that I want to add a new IP to pulpissimo and I'm a newbie so I don't know which exercise to follow first in your training course. As I see you have exercises like: configure_fll_debug_rtl, fullstack_ip_intergration, hello, memlayout_excersise, register_interface, runtime_new_config, runtime_reggen, runtime_trivial_driver, sdk_bootrom, sdk_driver_hal_header, sdk_driver_rt_symbols, sdk_reggen.
Thank you
