- EXAMPLE: If you want all functions except of network
- support you can write:
-
- #include "config_cmd_all.h"
- #undef CONFIG_CMD_NET
-
- Other Commands:
- fdt (flattened device tree) command: CONFIG_OF_LIBFDT
-
- Note: Don't enable the "icache" and "dcache" commands
- (configuration option CONFIG_CMD_CACHE) unless you know
- what you (and your U-Boot users) are doing. Data
- cache cannot be enabled on systems like the
- 8xx (where accesses to the IMMR region must be
- uncached), and it cannot be disabled on all other
- systems where we (mis-) use the data cache to hold an
- initial stack and some data.

-
- Removal of commands
If no commands are needed to boot, you can disable
CONFIG_CMDLINE to remove them. In this case, the command line
Allow generic access to the SPI bus on the Intel 8257x, for
example with the "sspi" command.

functional interfaces to some TPM commands.
CONFIG_USB_FUNCTION_DFU
This enables the USB portion of the DFU USB class
- CONFIG_CMD_DFU
- This enables the command "dfu" which is used to have
- U-Boot create a DFU class device via USB. This command
