* documentation: Moved "Yocto Project Source Repositories" sectionScott Rifenbark2017-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes [YOCTO #11630] The "Yocto Project Source Repositories" section is purely conceptual and thus does not belong in the reconstituted dev-manual, which is converting to a "how-to" manual. I have moved this section to the ref-manual under "The Yocto Project Development Environment" section. Moving the section affected several things. Three figures that where in the dev-manual were copied and moved to the figures folder of the ref-manual. This required deleting them from the dev-manual and adding them to the ref-manual. The makefile had to be edited to move those figures into the ref-manual and delete them from the latest version of the dev-manual in order for the tarball of files to be correct when the manuals are made. Links to anchors within the moved section had to be fixed in various manuals. Links to the main section "id" had to be fixed to point to the ref-manual manual.

* documentation: Fixed links for "metadata" term.Scott Rifenbark2017-06-221-1/+1
| | | | | | | | | | | | | Fixes [YOCTO #11630] Moving the "Yocto Project Terms" section from the dev-manual to the ref-manual broke the links to the "Metadata" term. I fixed these.

* documentation: Fixed links to "bitbake-term"Scott Rifenbark2017-06-221-1/+1
| | | | | | | | | | | | | | | | Fixes [YOCTO #11630] Moving the "Yocto Project Terms" section from the dev-manual to the ref-manual. Doing so caused all the links to the id "bitbake-term" to break. These had to be individually fixed. Discovered two unresolved references that were a consequence of moving that section to the ref-manual. These were fixed as well.

* kernel-dev: Provided better wording for recipe-space metadata sectionScott Rifenbark2017-03-311-2/+2
| | | | | | | | | | | | | Fixes [YOCTO #10946] Based on feedback, I made some minor rewrites to a sentence describing when you need to use a different form to get BitBake to pick up hierarchical data as kernel data.

* bsp-guide, kernel-dev: Updates to how kernel metadata is foundScott Rifenbark2017-03-311-163/+227
| | | | | | | | | | | | | | | | | | | | | | | | Fixes [YOCTO #10946] There was insufficient information in the combination of the BSP Guide and the Kernel Development Manual on just how to locate and use kernel metadata. * bsp-guide - Removed the detailed append file example for the kernel recipe. This is moved now to the chapter in the kernel manual that describes append files. * kernel-dev - Placed the example from the BSP Guide into the section that describes kernel append files. Cleaned up some terminology issues throughout chapter 3. Added information about how BitBake picks up kernel metadata when the metadata is in a hierarchical directory and not just a simple *.scc file.

* kernel-dev: Reorganized Kernel Metadata Location and Syntax sectionsScott Rifenbark2017-03-241-169/+169
| | | | | | | | | | | | | It seems that the two sections "Kernel Metadata Location" and "Kernel Metadata Syntax" were flipped regarding their order of apperance in the kernel-dev manual. I belive that syntax should be first and then followed by a discussion on the location. I have swapped these section's ordering in the manual.

* kernel-dev: Corrected linking format for two variables.Scott Rifenbark2017-03-241-4/+7
| | | | | | | | | | | | | Convention is to avoid using hyperlinks for variables that appear in <literallayout>/</literallalyout> coded blocks. I removed the links for the KERNEL_FEATURES and LINUX_KERNEL_TYPE variables, which appeared in a literal block and put the links into the context of the description.

| | | | | | | | | | | | | | | Fixes [YOCTO #8272] I re-wrote the section to basically consider kernel metadata coming from either inside the recipe (recipe-space) or from outside the recipe, which would be like a "kernel-cache". The re-write eliminated the term "in-tree" regarding where kernel metadata could reside.
