CONFIG_CMD_DHCP * DHCP support
CONFIG_CMD_DIAG * Diagnostics
CONFIG_CMD_DOC * Disk-On-Chip Support
+ CONFIG_CMD_DS4510 * ds4510 I2C gpio commands
+ CONFIG_CMD_DS4510_INFO * ds4510 I2C info command
+ CONFIG_CMD_DS4510_MEM * ds4510 I2C eeprom/sram commansd
+ CONFIG_CMD_DS4510_RST * ds4510 I2C rst command
CONFIG_CMD_DTT * Digital Therm and Thermostat
CONFIG_CMD_ECHO echo arguments
CONFIG_CMD_EEPROM * EEPROM read/write support
CONFIG_CMD_MII * MII utility commands
CONFIG_CMD_NAND * NAND support
CONFIG_CMD_NET bootp, tftpboot, rarpboot
+ CONFIG_CMD_PCA953X * PCA953x I2C gpio commands
+ CONFIG_CMD_PCA953X_INFO * PCA953x I2C gpio info command
CONFIG_CMD_PCI * pciinfo
CONFIG_CMD_PCMCIA * PCMCIA support
CONFIG_CMD_PING * send ICMP ECHO_REQUEST to network
Note that if the RTC uses I2C, then the I2C interface
must also be configured. See I2C Support, below.
+- GPIO Support:
+ CONFIG_PCA953X - use NXP's PCA953X series I2C GPIO
+ CONFIG_PCA953X_INFO - enable pca953x info command
+
+ Note that if the GPIO device uses I2C, then the I2C interface
+ must also be configured. See I2C Support, below.
+
- Timestamp Support:
When CONFIG_TIMESTAMP is selected, the timestamp
Bus on the MPC8260. But it should be not so difficult
to add this option to other architectures.
+ CONFIG_SOFT_I2C_READ_REPEATED_START
+
+ defining this will force the i2c_read() function in
+ the soft_i2c driver to perform an I2C repeated start
+ between writing the address pointer and reading the
+ data. If this define is omitted the default behaviour
+ of doing a stop-start sequence will be used. Most I2C
+ devices can use either method, but some require one or
+ the other.
- SPI Support: CONFIG_SPI
- CONFIG_SYS_LONGHELP: Defined when you want long help messages included;
undefine this when you're short of memory.
+- CONFIG_SYS_HELP_CMD_WIDTH: Defined when you want to override the default
+ width of the commands listed in the 'help' command output.
+
- CONFIG_SYS_PROMPT: This is what U-Boot prints on the console to
prompt for user input.
Useful on scripts which control the retry operation
themselves.
- npe_ucode - see CONFIG_IXP4XX_NPE_EXT_UCOD
- if set load address for the NPE microcode
+ npe_ucode - set load address for the NPE microcode
tftpsrcport - If this is set, the value is used for TFTP's
UDP source port.
