+- 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.
