CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA: Kernel low-level debugging messages via Tegra UART via ODMDATA

General informations

The Linux kernel configuration item CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA has multiple definitions:

Kernel low-level debugging messages via Tegra UART via ODMDATA found in arch/arm/Kconfig.debug

The configuration item CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA:

Help text

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.
