- CPU Module Type: (if CONFIG_COGENT is defined)
frequency is this value multiplied by 13 MHz.
CFG_MONAHANS_TURBO_RUN_MODE_RATIO
-
+
Defines the Monahans turbo mode to oscillator
ratio. Valid values are 1 (default if undefined) and
- 2. The core frequency as calculated above is multiplied
+ 2. The core frequency as calculated above is multiplied
by this value.
-
+
- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
The maximum size of the constructed OF tree.
OF_CPU - The proper name of the cpus node.
+ OF_SOC - The proper name of the soc node.
OF_TBCLK - The timebase frequency.
+ OF_STDOUT_PATH - The path to the console device
+
+ CONFIG_OF_HAS_BD_T
+
+ The resulting flat device tree will have a copy of the bd_t.
+ Space should be pre-allocated in the dts for the bd_t.
+
+ CONFIG_OF_HAS_UBOOT_ENV
+
+ The resulting flat device tree will have a copy of u-boot's
+ environment variables
+
+ CONFIG_OF_BOARD_SETUP
+
+ Board code has addition modification that it wants to make
+ to the flat device tree before handing it off to the kernel
+
+ CONFIG_OF_BOOT_CPU
+
+ This define fills in the correct boot cpu in the boot
+ param header, the default value is zero if undefined.
- Serial Ports:
CFG_PL010_SERIAL
CFG_CMD_DIAG * Diagnostics
CFG_CMD_DOC * Disk-On-Chip Support
CFG_CMD_DTT * Digital Therm and Thermostat
- CFG_CMD_ECHO * echo arguments

of the backslashes before semicolons and special
symbols.
+- Commandline Editing and History:
+ CONFIG_CMDLINE_EDITING
+
+ Enable editiong and History functions for interactive
+ commandline input operations
+
- Default Environment:
CONFIG_EXTRA_ENV_SETTINGS
- CFG_MALLOC_LEN:
Size of DRAM reserved for malloc() use.
+- CFG_BOOTM_LEN:
+ Normally compressed uImages are limited to an
+ uncompressed size of 8 MBytes. If this is not enough,
+ you can define CFG_BOOTM_LEN in your board config file
+ to adjust this setting to your needs.
+
- CFG_BOOTMAPSZ:
Maximum size of memory mapped by the startup code of
the Linux kernel; all data that must be processed by
bash#
+Boot Linux and pass a flat device tree:
+-----------
+
+First, U-Boot must be compiled with the appropriate defines. See the section
+titled "Linux Kernel Interface" above for a more in depth explanation. The
+following is an example of how to start a kernel and pass an updated
+flat device tree:

More About U-Boot Image Types:
------------------------------
==> U-Boot will use R8 to hold a pointer to the global data
+NOTE: DECLARE_GLOBAL_DATA_PTR must be used with file-global scope,
+or current versions of GCC may "optimize" the code too much.
