[meta-fsl-arm PATCH v5 0/6] Dynamically choose between built-in or external Vivante GPU kernel driver

[Otavio Salvador]

This patchset implements support to dynamically choose between
built-in or external Vivante GPU kernel driver.

By default, the external Vivante GPU kernel module is used, however
every machine can have its own choice for this, or distros can
override the default value if needed.

The following options are supported:

  MACHINE_HAS_VIVANTE_KERNEL_DRIVER_SUPPORT

     Machine does or does not have support for the Vivante kernel
     driver, options are:

       0 - machine does not have Vivante GPU driver support
       1 - machine has Vivante GPU driver support

  MACHINE_USES_VIVANTE_KERNEL_DRIVER_MODULE

      Machine uses the Vivante kernel driver as module, options are:

       0 - enable the builtin kernel driver module
       1 - enable the external kernel module

The patches included in this patchset are:

Changes in v5:
- Skip package when machine does not have Vivante kernel support
- Add SoC default for kernel support in imx-base.inc

Changes in v4:
- Uses intermediate variable to fix override in machine definition files
- Silence the warning about missing build-dependency

Changes in v3:
- improve class documentation and commit log according to Ann suggestions
- New patch

Changes in v2:
- Improve commit log (Daiane)
- improve commit log and class documentation for
  MACHINE_HAS_VIVANTE_KERNEL_DRIVER_SUPPORT (Daiane)
- Improve commit log and patch header for clearness (Daiane)

[meta-fsl-arm PATCH v5 1/6] kernel-module-mcc: move to kernel-modules subdir

[Otavio Salvador]

There are more kernel modules which are going to be packaged so it
makes sense to have them all in same subdirectory.

[meta-fsl-arm PATCH v5 4/6] Enable Vivante kernel driver dynamic provider

[Otavio Salvador]

The linux-imx.inc based kernels now can dynamically provide the
Vivante kernel driver and satisfy the runtime dependency added for the
Vivante GPU user space libraries. The beauty of this solution is that
it makes ease for 3rd party kernel to reuse the same infrastructure
and use the external module easily.

[meta-fsl-arm PATCH v5 5/6] linux-fslc-mx6: Bump revision to 2574f81

[Otavio Salvador]

This upgrades the kernel fork for the 3.14.51 stable release. Another
change is the inclusion of:

22f6925 arm: Export cache flush management symbols when !MULTI_CACHE

This fixes following error:

galcore: Unknown symbol v7_dma_map_area (err 0)
galcore: Unknown symbol v7_dma_flush_range (err 0)

When using the Vivante GPU module as a module.

[meta-fsl-arm PATCH v5 6/6] kernel-module-imx-gpu-viv: Fix build against 3.14-based kernels

[Otavio Salvador]

The build fail about the bus frequency header (linux/busfreq-imx6.h)
not being found is caused by the mistaken check for the wrong kernel
version.

This patch fixes it by adding the right kernel version to be checked.
