@@ -644,23 +644,6 @@ The following options need to be configured: 'Sane' compilers will generate smaller code if CONFIG_PRE_CON_BUF_SZ is a power of 2 -- 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.
