- CONFIG_OF_FLAT_TREE
+ CONFIG_OF_LIBFDT / CONFIG_OF_FLAT_TREE
New kernel versions are expecting firmware settings to be
- passed using flat open firmware trees.
- The environment variable "disable_of", when set, disables this
- functionality.
+ passed using flattened device trees (based on open firmware
+ concepts).
+
+ CONFIG_OF_LIBFDT
+ * New libfdt-based support
+ * Adds the "fdt" command
+ * The bootm command does _not_ modify the fdt
+
+ CONFIG_OF_FLAT_TREE
+ * Deprecated, see CONFIG_OF_LIBFDT
+ * Original ft_build.c-based support
+ * Automatically modifies the dft as part of the bootm command
+ * The environment variable "disable_of", when set,
+ disables this functionality.
CONFIG_OF_FLAT_TREE_MAX_SIZE
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_LIBFDT - enables the "fdt bd_t" command
+ * CONFIG_OF_FLAT_TREE - 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_LIBFDT - enables the "fdt bd_t" command
+ * CONFIG_OF_FLAT_TREE - The resulting flat device tree

CONFIG_OF_BOARD_SETUP
#define CONFIG_COMMANDS (CFG_CMD_ALL & ~CFG_CMD_NET)
+ Other Commands:
+ fdt (flattened device tree) command: CONFIG_OF_LIBFDT
Note: Don't enable the "icache" and "dcache" commands
(configuration option CFG_CMD_CACHE) unless you know
clock chips. See common/cmd_i2c.c for a description of the
command line interface.
- CONFIG_HARD_I2C selects the CPM hardware driver for I2C.
+ CONFIG_I2C_CMD_TREE is a recommended option that places
+ all I2C commands under a single 'i2c' root command. The
+ older 'imm', 'imd', 'iprobe' etc. commands are considered
+ deprecated and may disappear in the future.
+
+ CONFIG_HARD_I2C selects a hardware I2C controller.
CONFIG_SOFT_I2C configures u-boot to use a software (aka
bit-banging) driver instead of CPM or similar hardware
in u-boot bd_info structure based on u-boot environment
variable "i2cfast". (see also i2cfast)
+ CONFIG_I2C_MULTI_BUS
+
+ This option allows the use of multiple I2C buses, each of which
+ must have a controller. At any point in time, only one bus is
+ active. To switch to a different bus, use the 'i2c dev' command.
+ Note that bus numbering is zero-based.
+
+ CFG_I2C_NOPROBES
+
+ This option specifies a list of I2C devices that will be skipped
+ when the 'i2c probe' command is issued (or 'iprobe' using the legacy
+ command). If CONFIG_I2C_MULTI_BUS is set, specify a list of bus-device
+ pairs. Otherwise, specify a 1D array of device addresses
+
+ e.g.
+ #undef CONFIG_I2C_MULTI_BUS
+ #define CFG_I2C_NOPROBES {0x50,0x68}
+
+ will skip addresses 0x50 and 0x68 on a board with one I2C bus
+
+ #define CONFIG_I2C_MULTI_BUS
+ #define CFG_I2C_MULTI_NOPROBES {{0,0x50},{0,0x68},{1,0x54}}
+
+ will skip addresses 0x50 and 0x68 on bus 0 and address 0x54 on bus 1
+
+ CFG_SPD_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for DDR SPD.
+ If not defined, then U-Boot assumes that SPD is on I2C bus 0.
+
+ CFG_RTC_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for the RTC.
+ If not defined, then U-Boot assumes that RTC is on I2C bus 0.
+
+ CFG_DTT_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for the DTT.
+ If not defined, then U-Boot assumes that DTT is on I2C bus 0.
+
+ CONFIG_FSL_I2C
+
+ Define this option if you want to use Freescale's I2C driver in
+ drivers/fsl_i2c.c.
+
+
- SPI Support: CONFIG_SPI
Enables SPI driver (so far only tested with
default value of 5 is used.
- Command Interpreter:
- CFG_AUTO_COMPLETE
+ CONFIG_AUTO_COMPLETE
Enable auto completion of commands using TAB.
+ Note that this feature has NOT been implemented yet
+ for the "hush" shell.
+
+
CFG_HUSH_PARSER
Define this variable to enable the "hush" shell (from
CFG_POCMR2_MASK_ATTRIB: (MPC826x only)
Overrides the default PCI memory map in cpu/mpc8260/pci.c if set.
+- CONFIG_SPD_EEPROM
+ Get DDR timing information from an I2C EEPROM. Common with pluggable
+ memory modules such as SODIMMs
+ SPD_EEPROM_ADDRESS
+ I2C address of the SPD EEPROM
+
+- CFG_SPD_BUS_NUM
+ If SPD EEPROM is on an I2C bus other than the first one, specify here.
+ Note that the value must resolve to something your driver can deal with.
+
+- CFG_83XX_DDR_USES_CS0
+ Only for 83xx systems. If specified, then DDR should be configured
+ using CS0 and CS1 instead of CS2 and CS3.
+
+- CFG_83XX_DDR_USES_CS0
+ Only for 83xx systems. If specified, then DDR should be configured
+ using CS0 and CS1 instead of CS2 and CS3.
+
- CONFIG_ETHER_ON_FEC[12]
