We enable this feature on UARTD for Seaboard. This ensures that a message is printed if CONFIG_OF_CONTROL is in use and a valid device tree is not available (provided the Seaboard variant uses UARTD for console).
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v2: - Correctly use only selected UARTs in tegra_pre_console_panic() - Only use UARTD for Seaboard
