- 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.
-
- 'Sane' compilers will generate smaller code if
- CONFIG_PRE_CON_BUF_SZ is a power of 2

example, some LED's) on your board. At the moment,
the following checkpoints are implemented:
-- Standalone program support:
- CONFIG_STANDALONE_LOAD_ADDR
-
- This option allows to define board specific values
- for the address where standalone program gets loaded,
- thus overwriting the architecutre dependent default
- settings.
-
-- Frame Buffer Address:
- CONFIG_FB_ADDR
-
- Define CONFIG_FB_ADDR if you want to use specific address for
- frame buffer.
- Then system will reserve the frame buffer address to defined address
- instead of lcd_setmem (this function grab the memory for frame buffer
- by panel's size).
-
- Please see board_init_f function.
-
- If you want this config option then,
- please define it at your board config file
