[PATCH v9 4/9] arm: ks8695: Migrate debug_ll macros to shared directory

Daniel Thompson daniel.thompson at linaro.org
Tue Aug 19 08:16:42 PDT 2014


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.
