[PATCH 15/15] powerpc: kill PPC_OF

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 ke

[PATCH 14/15] usb: kconfig: replace PPC_OF with PPC

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 Signed-off-b
