Subject[PATCH] ARM: debug: qcom: make UART address selection configuration option
Date
From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

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.

Signed-off-by: Ivan T. Ivanov <iivanov@mm-sol.com>
