1. no public documentation
2. How match is it different to this:

        config DEBUG_MSM_UART
                bool "Kernel low-level debugging messages via MSM UART"
                depends on ARCH_MSM
                help
                  Say Y here if you want the debug print routines to direct
                  their output to the serial port on MSM devices.

                  ARCH                DEBUG_UART_PHYS   DEBUG_UART_BASE   #
                  MSM7X00A, QSD8X50   0xa9a00000        0xe1000000
  UART1
                  MSM7X00A, QSD8X50   0xa9b00000        0xe1000000
  UART2
                  MSM7X00A, QSD8X50   0xa9c00000        0xe1000000
  UART3

                  MSM7X30             0xaca00000        0xe1000000
  UART1
                  MSM7X30             0xacb00000        0xe1000000
  UART2
                  MSM7X30             0xacc00000        0xe1000000
  UART3

                  Please adjust DEBUG_UART_PHYS and DEBUG_UART_BASE
configuration
                  options based on your needs.

        config DEBUG_QCOM_UARTDM
                bool "Kernel low-level debugging messages via QCOM UARTDM"
                depends on ARCH_QCOM
                help
                  Say Y here if you want the debug print routines to direct
                  their output to the serial port on Qualcomm devices.

                  ARCH      DEBUG_UART_PHYS   DEBUG_UART_BASE
                  APQ8084   0xf995e000        0xfa75e000
                  MSM8X60   0x19c40000        0xf0040000
                  MSM8960   0x16440000        0xf0040000
                  MSM8974   0xf991e000        0xfa71e000

                  Please adjust DEBUG_UART_PHYS and DEBUG_UART_BASE
configuration
                  options based on your needs.
