ARM: keystone: Add minimal TI Keystone platform support Texas Instruments Keystone family of multi-core devices are based on ARM Cortex A15. Patch adds basic definitions for a new Keystone sub-architecture in ARM. The TCI66xxK2H Communications Infrastructure Keystone SoCs are member of the C66x family based on TI's new KeyStone 2 multi-core SoC Architecture designed specifically for high performance wireless and networking infrastructure applications. The SOCs contains many subsystems like Cortex A15 ARM CorePacs, C66XX DSP CorePacs, MSMC memory controller, Tera Net bus, IP Network, Navigator, Hyperlink, 1G/10G Ethernet, Radio layers and queue based communication systems.

ARM: keystone requires ARM_PATCH_PHYS_VIRT The dynamic relocation that the keystone platform performs only works if we can pick the phys offset at boot time. It's possible that there is another solution for this, but this is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT are not portable across platforms, and I see no reason why anyone would run a kernel without ARM_PATCH_PHYS_VIRT on keystone.

ARM: keystone: enable big endian support Keystone code is big endian compatible, so mark it as one that supports big endian. Note this patch just allows to select Big endian build for ARCH_KEYSTONE, but it does not enable BE by default.
