-- Pre-Console Buffer:
- Prior to the console being initialised (i.e. serial UART
- initialised etc) all console output is silently discarded.
- Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
- buffer any console messages prior to the console being
- initialised to a buffer of size CONFIG_PRE_CON_BUF_SZ
- bytes located at CONFIG_PRE_CON_BUF_ADDR. The buffer is
- a circular buffer, so if more than CONFIG_PRE_CON_BUF_SZ
- bytes are output before the console is initialised, the
- earlier bytes are discarded.
-
- Note that when printing the buffer a copy is made on the
- stack so CONFIG_PRE_CON_BUF_SZ must fit on the stack.
-
- 'Sane' compilers will generate smaller code if
- CONFIG_PRE_CON_BUF_SZ is a power of 2
-
-- Boot Delay: CONFIG_BOOTDELAY - in seconds
- Delay before automatically booting the default image;
- set to -1 to disable autoboot.
- set to -2 to autoboot with no delay and not check for abort
- (even when CONFIG_ZERO_BOOTDELAY_CHECK is defined).
-
- See doc/README.autoboot for these options that
- work with CONFIG_BOOTDELAY. None are required.
