Building NuttX on Chrome OS

[Gregory Nutt]

I have been tinkering with Chrome OS recently just to keep myself 
informed.  If anyone cares, I have been able to build and run the NuttX 
simulator on Chrome OS.  Debian Linux is available on Chrome OS, so why 
is this a thing?

- A ChromeBook is a highly memory constrained platform and it is 
primarily web based.  So a lot of the effort was just getting resources 
in place to perform the Debian build on the ChromeBook.

- ChromeBooks are also highly secured.  Debian runs inside of a virtual 
machine "container" (called penguin) and all I/O is performed through a 
Plan 9 server (called Crostini).  Configuring the container to support 
the additional resources was most of that effort.

Other than being a fun way to spend a couple of days, I am not sure if 
building NuttX on a ChromeBook is a useful thing or not. Because of its 
complexity, I don't think it is would be the first choice of a 
development environment.  But also because of the very low cost of 
Chromebooks, it is also one of the cheapest NuttX development 
environments that you could get.
