Bug 10975

edwin.plauchu.camacho: There is a typo within section 2.4.3 of implementation document https://github.com/01org/DAFT/blob/master/README.MD
edwin.plauchu.camacho: tftp0x8000000                               
edwin.plauchu.camacho: it should have a blank space between tftp and 0x8000000                        

simo.kuusela: I'll fix the typo, must have been really annoying, not sure how I have copied the uEnv wrong to the guide :s

Eliminated dhcp contamination inside DUT lan.

"""DAFT is pretty tied to the dnsmasq files so far. """
At the moment It is a justified approach due to DAFT is always inquiring dnsmasq's data associated with ip and mac addresses that were granted by dnsmasq. 

That's why prior dhcp server upon DUT lan has been turned off.

From this point onward we are using dnsmasq as the DUT lan dhcp server.

Uboot config has been verified as ok

Beagle Bone Black is booting its kernel through TFTP and mounting its file system with NFS.
The verification was performed with a small hub connected to GDC's auto builder bridge.

BBB file system utilized during this implementation

Connected homemade "normally closed" relay to BBB

Configuration for relay cables:
Green - 5V (from the board)
White/Green - GND (from the board)
Blue - Signal (min 3.3V max 5V, from the board)

Further details about the relay circuits can be found at https://wiki.yoctoproject.org/wiki/Arduino_Single_power_control_unit

Latest version of DAFT has been implemented in GDC as per plan 
but it is not completely functional to collaborate with auto builder.

Several modifications in DAFT are required.

-

1) Decouple test injection mechanism, it is currently not decoupled from DAFT. Once It could be made, auto builder should play as a test injector entity through the newer DAFT’s service. ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=11215 )

2) Newer test specification format needed, because of the current one is not aware if a test would be runnable or not upon specific DUT. ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=11219 )

3) Convert DAFT in a service available for any Yocto auto builder worker ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=11216 )

4) Merged devauto library with DAFT. Devauto is a library developed in GDC one year ago. Such library offers common interfaces and one config file to operate power switches and keyboard emulators through proxy objects. ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=11218 )

5) Remove DAFT's DHCP server dependency. It would work OK in the past when it was AFT ("the centralize approach") but today we are suffering with needless auto discovering of devices which are not required at all. ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=11217 )

6) Update DAFT implementation manual
