Finish the piratepython configuration

[ali1234]

Things needed to make this happen:

• Move pymtpd inside the piratepython package.
• Split pymtpd into functionfs and gadgetfs parts.
• Fix pymtpd for Windows.
• Fix pymtpd for Mac.
• Add users for mtp and python code.
• Add systemd mount for /boot, read-only for python user, r/w for mtp user.
• Check if the mount is even available and if not run from ramdisk.
• Add gadgetfs for two serial ports.
• Add a getty on one serial port.
• Redirect python output to the other serial port.

What would be your preference for adding additional kernel config options? PiratePython and Keybow use ConfigFs and a bunch of the associated modules to set up the appropriate interfaces.

It looks like the config.py can specify a list of kernels, would it be appropriate to prepare a kernel config specific to this config and list only that? (Keybow, in particular, only uses "kernel" and not "kernel7" since it targets only Pi Zero for the most part.)

May as well just change the configs that are there. The current USB device mode configuration is not important for anything and probably doesn't work. Also the kernels all need updating anyway.

You should include the other kernels if possible though. Especially as Pi 4 has USB device mode.

[Gadgetoid]

That's a fair point, actually, Pi 4 can host Keybow and/or PiratePython.

Right now I've got a config derived from the existing kernel.config that I'm hacking on. Remembering what to enable and how is eluding me. It's been a long time!

Current status- I seem to have most of the required modules but am missing devices in /sys/class/udc so I have nothing to bind the USB config to. Will have to bash my head against this some more, later!
