[PATCH v8 4/9] arm: ks8695: Migrate debug_ll macros to shared directory

Daniel Thompson
2014-08-19T14:51:30Z

As part of the migration a couple of uart definitions have been copied
from of the platform specific header files.

Note that, in order to keep oldconfig working nicely we must defer the
removal of arch/arm/mach-ks8695/include/mach/debug-macro.S until
DEBUG_LL_UART_NONE has been removed.
