ARC: [TB10x] Add support for TB10x platform
Infrastructure required to make the Linux kernel compile and boot on the Abilis Systems TB10x series of SOCs based on ARC700 CPUs: - Kmake related files (Kconfig, Makefile, tb10x_defconfig) - TB10x platform initialisation Signed-off-by: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Pierrick Hascoet <pierrick.hascoet@abilis.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Support for platforms based on the TB10x home media gateway SOC by

Abilis Systems. TB10x is based on the ARC700 CPU architecture.

Say Y if you are building a kernel for one of the SOCs in this

series (e.g. TB100 or TB101). If in doubt say N.
