From 48167d4a55890a783cc8b1590bc8071253ae4b83 Mon Sep 17 00:00:00 2001 From: "Ivan T. Ivanov" Date: Mon, 14 Apr 2014 16:47:34 +0300 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. Signed-off-by: Ivan T.
