'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. These are defined in
