Description:
A generic interface for executing OLPC Embedded Controller commands and
reading their responses.
To execute a command, write data with the format: CC:N A A A A
CC is the (hex) command, N is the count of expected reply bytes, and A A A A
are optional (hex) arguments.
To read the response (if any), read from the generic node after executing
a command. Hex reply bytes will be returned, *whether or not* they came from
the immediately previous command.
