Please note, that, although 'Blaze' board is very close to 'SDP' board,
there are quite big differences comparing to 'Blaze Tablet' board.
At least:
 - LCD panels
 - touchscreen controllers
 - LEDs
 - Keypad (on 'Blaze') / gpio keys (on 'Blaze Tablet')
 - Sensors
 - HS USB Host related stuff
 - cameras (there is no embedded cameras on 'Blaze Tablet' board)

As per my point of view, next should be done:
1) Add the DTS file for BlazeTablet board
2) Figure out what is common for both and move it to some common file
(if that makes sense)

I'm currently working on step '#1'. So after that step #2 should not
be an issue for us.

Best regards,
Ruslan
