[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2013-12-04 19:56 +0100, Thomas Petazzoni spake thusly:
> This commit allows the BR2_EXTERNAL directory to contain Config.in and
> Makefile code, which gets integrated into the Buildroot build logic:
> 
>  - Buildroot automatically includes the $BR2_EXTERNAL/Config.in in the
>    top-level configuration menu.
> 
>  - Buildroot automatically includes the BR2_EXTERNAL/external.mk in
>    the build logic, so it can for example be used to include other .mk
>    files that define package recipes.
> 
> This is typically intended to be used to create target packages in the
> BR2_EXTERNAL directory, but can also be used for bootloaders, host
> packages, or other custom make logic.
> 
> We also add a dummy Config.in file in support/dummy-external/ to
> ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an
> existing file even when BR2_EXTERNAL is not used by the user.
