[PATCH v2 02/11] fbdev: aty128fb: replace PPC_OF with PPC

[Kevin Hao]

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC.

[PATCH v2 06/11] fbdev: riva: remove the dependency on PPC_OF

[Kevin Hao]

The OF functionality has moved to a common place and be used by many
archs. So we don't need to include the ppc arch specific header files
and depend on PPC_OF option any more. This is a preparation for
killing PPC_OF.

[PATCH v2 08/11] fbdev: kconfig: replace PPC_OF with PPC

[Kevin Hao]

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC.

[PATCH v2 11/11] powerpc: kill PPC_OF

[Kevin Hao]

We have set CONFIG_PPC_OF to always 'y' in commit 0a498d96a332
("powerpc: set CONFIG_PPC_OF=y always for ARCH=powerpc") nine years
ago. And the arch/ppc also has gone away for many years. The OF
functionality was also moved to a common place and be used by many
archs. So it does make no sense to keep such a option in the current
kernel. Just kill it.
