This adds another test program to use with the EC connected to
the build host via an FTDI USB-to-SPI adapater, This program
sends an EC_CMD_HELLO host command to the EC. Options exist to
display the bytes transferred over the SPI interface, and to
truncate the message before its complete, to see how the EC reacts.
BUG=chrome-os-partner:40969
BRANCH=none
TEST=make buildall
To try out the new test program:
cd extra/sps_errs
make
./prog
./prog -v
./prog -v -c 22
