	help
	  Automatically determines which UART to use for low-level debug based
	  on the ODMDATA value. This value is part of the BCT, and is written
	  to the boot memory device using nvflash, or other flashing tool.
	  When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
	  0/1/2/3/4 are UART A/B/C/D/E.

config TEGRA_DEBUG_UART_AUTO_SCRATCH
	bool "Via UART scratch register"
	help
	  Automatically determines which UART to use for low-level debug based
	  on the UART scratch register value. Some bootloaders put ASCII 'D'
	  in this register when they initialize their own console UART output.
	  Using this option allows the kernel to automatically pick the same
	  UART.
