+- Pre-console putc():
+		Prior to the console being initialised, console output is
+		normally silently discarded. This can be annoying if a
+		panic() happens in this time.
+
+		If the CONFIG_PRE_CONSOLE_PUTC option is defined, then
+		U-Boot will call board_pre_console_putc() for each output
+		character in this case, This function should try to output
+		the character if possible, perhaps on all available UARTs
+		(it will need to do this directly, since the console code
+		is not functional yet). Note that if the panic happens
+		early enough, then it is possible that board_init_f()
+		(or even arch_cpu_init() on ARM) has not been called yet.
+		You should init all clocks, GPIOs, etc. that are needed
+		to get the character out. Baud rates will need to default
+		to something sensible.
+
+- Safe printf() functions
+		Define CONFIG_SYS_VSNPRINTF to compile in safe versions of
+		the printf() functions. These are defined in
+		include/vsprintf.h and include snprintf(), vsnprintf() and
+		so on. Code size increase is approximately 300-500 bytes.
+		If this option is not given then these functions will
+		silently discard their buffer size argument - this means
+		you are not getting any overflow checking in this case.

+- ULPI Layer Support:
+		The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
+		the generic ULPI layer. The generic layer accesses the ULPI PHY

+		the viewport enabled. Currently only Chipidea/ARC based

+		To enable the ULPI layer support, define CONFIG_USB_ULPI and
