- U-Boot Version:
CONFIG_VERSION_VARIABLE
If this variable is defined, an environment variable
requests. Increasing this will allow U-Boot to accept offers
from a BOOTP client in networks with unusually high latency.
+- BOOTP Random transaction ID:
+ CONFIG_BOOTP_RANDOM_ID
+
+ The standard algorithm to generate a DHCP/BOOTP transaction ID
+ by using the MAC address and the current time stamp may not
+ quite unlikely produce duplicate transaction IDs from different
+ clients in the same network. This option creates a transaction
+ ID using the rand() function. Provided that the RNG has been
+ seeded well, this should guarantee unique transaction IDs
+ always.

- DHCP Advanced Options:
You can fine tune the DHCP functionality by defining
CONFIG_BOOTP_* symbols:
This enables the RSA algorithm used for FIT image verification
in U-Boot. See doc/uImage.FIT/signature.txt for more information.

- bootcount support:
CONFIG_BOOTCOUNT_LIMIT
If defined, specified the chip address of the EEPROM device.
The default address is zero.
+ - CONFIG_SYS_I2C_EEPROM_BUS:
+ If defined, specified the i2c bus of the EEPROM device.

- CONFIG_SYS_EEPROM_PAGE_WRITE_BITS:
If defined, the number of bits used to address bytes in a
single page in the EEPROM device. A 64 byte page, for example
