Subject: manual/user guide/customization: add section with recommended dir structure
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9c09fc601775120f1e504e5b2b77d1cc3bb5bb97;p=buildroot.git

manual/user guide/customization: add section with recommended dir structure

Although the user is free to choose where to put project-specific files, the
presentation 'Using Buildroot for real projects' [1] first described a
certain recommendation.
This patch briefly describes this recommendation in the form of a directory
structure overview, the details will be added in subsequent patches.

Since the section on BR2_EXTERNAL is logically connected to the directory
structure, this section is moved right after it.

+=== 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.

+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.
