*	arc: check caches existence before use	Igor Guryanov	2015-01-15	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Some cache operations ({i\|d}cache_{enable\|disable\|status} or flush_dcache_all) are built and used even if CONFIG_SYS_{I\|D}CACHE_OFF is set. This is required for force disable of caches on early boot. What if something was executed before U-boot and enabled caches (low-level bootloaders, previously run kernel etc.)? But if CPU doesn't really have caches any attempt to access cache-related AUX registers triggers instruction error exception. So for convenience we'll try to avoid exceptions by checking if CPU actually has caches (we check separately data and instruction cache existence) at all.

*	arc: add architecture header files	Alexey Brodkin	2014-02-07	1	-0/+55
	These are header files used by ARC700 architecture. Also note that "arch-arc700/hardware.h" is only required for compilation of "designware_i2c" driver which refers to "asm/arch/hardware.h". It would be good to fix mentioned driver sometime soon but it will cause changes in ARM board configs that use "designware_i2c".
