+- 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

+ Enable the Freescale DIU video driver. Reference boards for
SOCs that have a DIU should define this macro to enable DIU
support, and should also define these other macros:
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

+- CONFIG_SYS_CCSRBAR_DEFAULT:
+ Default (power-on reset) physical address of CCSR on Freescale
+ PowerPC SOCs.
+
+- CONFIG_SYS_CCSRBAR:
+ Virtual address of CCSR. On a 32-bit build, this is typically
+ the same value as CONFIG_SYS_CCSRBAR_DEFAULT.
+
+ CONFIG_SYS_DEFAULT_IMMR must also be set to this value,
+ for cross-platform code that uses that macro instead.
+
+- CONFIG_SYS_CCSRBAR_PHYS:
+ Physical address of CCSR. CCSR can be relocated to a new
+ physical address, if desired. In this case, this macro should
+ be set to that address. Otherwise, it should be set to the
+ same value as CONFIG_SYS_CCSRBAR_DEFAULT. For example, CCSR
+ is typically relocated on 36-bit builds. It is recommended
+ that this macro be defined via the _HIGH and _LOW macros:
+
+ #define CONFIG_SYS_CCSRBAR_PHYS ((CONFIG_SYS_CCSRBAR_PHYS_HIGH
+ * 1ull) << 32 | CONFIG_SYS_CCSRBAR_PHYS_LOW)
+
+- CONFIG_SYS_CCSRBAR_PHYS_HIGH:
+ Bits 33-36 of CONFIG_SYS_CCSRBAR_PHYS. This value is typically
+ either 0 (32-bit build) or 0xF (36-bit build). This macro is
+ used in assembly code, so it must not contain typecasts or
+ integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSRBAR_PHYS_LOW:
+ Lower 32-bits of CONFIG_SYS_CCSRBAR_PHYS. This macro is
+ used in assembly code, so it must not contain typecasts or
+ integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSR_DO_NOT_RELOCATE:
+ If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
+ forced to a value that ensures that CCSR is not relocated.
