Merged in alinjerpelea/nuttx (pull request #963) Move boards to boards folder * boards: rename configs folder to boards This is the proposed layout after the change: boards: - folder containing board folders <board>: - name of each board drivers: - extra drivers specific for platform include: - header files for the boars scripts: - extra scripts specific for platform src: - board specific code tools: - extra tools specific for platform <config>: - board specific configuration(s) Note: <xxx> names are dependent on platform This is a logical change to aim to the arch layout but this is a huge change it should be done in several steps to lower the risk.
