All three modes are in place.

This is patch 2/4. Command syntax:
$ sudo ./tegrarcm --ml_rcm <ml> --pkc <keyfile> --bootloader <bootloader>

User still needs to put device in recovery mode so that tegrarcm can detect and figure out what soc. Otherwise, we need to add one more parameter for soc.

> b) Read signed files, send them to HW.

This is patch 3/4. Command syntax:
$ sudo ./tegrarcm --miniloader <signed_ml> --signed --bct <bct> --bootloader <bootloader> --loadaddr <addr> 

> c) Sign data on-the-fly, while sending it to HW.

This is patch 1/4. Command syntax:
$ sudo ./tegrarcm --pkc <keyfile> --bct <bct> --bootloader <bootloader> --loadaddr <addr>
