This patch reworks the section on BR2_EXTERNAL as follows: - move note about upstreaming to the chapter introduction - streamline the section with the previously added section 'Recommended directory structure', avoiding duplication. - use $(BR2_EXTERNAL) rather than BR2_EXTERNAL when referring to file paths. - some general rewording Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

=== Recommended directory structure
|
|
|
|
When customizing Buildroot for your project, you will be creating one or
|
|
more project-specific files that need to be stored somewhere. While most
|
|
of these files could be placed in _any_ location as their path is to be
|
|
specified in the Buildroot configuration, the Buildroot developers
|
|
recommend a specific directory structure which is described in this
|
|
section.
|
|
|
|
Orthogonal to this directory structure, you can choose _where_ you place
|
|
this structure itself: either inside the Buildroot tree, or outside of
|
|
it using +BR2_EXTERNAL+. Both options are valid, the choice is up to you.

Details on the files shown above are given further in this chapter.

|
|
Note: if you choose to place this structure outside of the Buildroot
|
|
tree using +BR2_EXTERNAL+, the <company> and possibly <boardname>
|
|
components may be superfluous and can be left out.
