+From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

+Subject: [PATCH 097/182] ARM: debug: qcom: make UART address selection
+ configuration option
+
+Separate Qualcomm low-level debugging UART to two options.
+
+DEBUG_MSM_UART is used in earlier non-multi platform arches,
+like MSM7X00A, QSD8X50 and MSM7X30.
+
+DEBUG_QCOM_UARTDM is used in multi-plafrom arches and have
+embedded data mover.
+
+Make DEBUG_UART_PHYS and DEBUG_UART_BASE user adjustable by
+Kconfig menu.
