[meta-freescale] The Yocto layer re-architect for FSL QorIQ SDK

[zhenhua.luo at freescale.com]

Hi all,



Along with the Layerscape ARM platforms support in QorIQ SDK, there are more and more common recipes for QorIQ PPC targets and QorIQ Layerscape ARM targets, to avoid the duplicated recipes which are maintained in fsl-arm and fsl-ppc layer separately, and make the layers hierarchical for FSL QorIQ SDK, the unified top layer(meta-fsl-qoriq) and corresponding sub-layers(meta-arm and meta-ppc) mechanism is proposed.



Following is the structure of the meta-fsl-qoriq layer.

meta-fsl-qoriq

|--- common                   # the common recipes for QorIQ ARM and PPC targets

|--- conf

|    |--- layar.conf          # the layer conf file of top layer

|--- COPYING                  # the license file of FSL QorIQ layer

|--- meta-arm                 # the sub-layer for recipes specific to QorIQ ARM targets

|    |--- conf

|    |    |--- layer.conf     # the layer conf file of QorIQ ARM sub-layer

|    |    |--- machine        # the machine conf files of QorIQ ARM platforms

|    |--- README              # README of QorIQ ARM sub-layer

|    |--- recipes-...           # the recipes of QorIQ ARM targets

|--- meta-ppc                 # the sub-layer for recipes specific to QorIQ PPC targets

|    |--- conf

|    |    |--- layer.conf     # the layer conf file of QorIQ PPC sub-layer

|    |    |--- machine        # the machine conf files of QorIQ PPC platforms

|    |--- README              # README of QorIQ PPC sub-layer

|    |--- recipes-...           # the recipes of QorIQ PPC targets

|--- meta-...                   # other layers for QorIQ SDK support, e.g. meta-toolchain

|--- README                   # README of top layer



The meta-fsl-ppc layer will be retired and replaced by the new meta-fsl-qoriq layer.



Can you please review? Your comments and suggestions are welcome.
