Some PHY like Intel LXT971A need extra delay after
command issued before MII status register can be read
-- IP address:
- CONFIG_IPADDR
-
- Define a default value for the IP address to use for
- the default Ethernet interface, in case this is not
- determined through e.g. bootp.
- (Environment variable "ipaddr")
-
-- Server IP address:
- CONFIG_SERVERIP
-
- Defines a default value for the IP address of a TFTP
- server to contact when using the "tftboot" command.
- (Environment variable "serverip")
-
-- Gateway IP address:
- CONFIG_GATEWAYIP
-
- Defines a default value for the IP address of the
- default router where packets to other networks are
- sent to.
- (Environment variable "gatewayip")
-
-- Subnet mask:
- CONFIG_NETMASK
-

- BOOTP Recovery Mode:
CONFIG_BOOTP_RANDOM_DELAY
- CONFIG_SYS_FLASH_USE_BUFFER_WRITE
Use buffered writes to flash.
-- CONFIG_FLASH_SPANSION_S29WS_N
- s29ws-n MirrorBit flash has non-standard addresses for buffered
- write commands.
-
-- CONFIG_FLASH_VERIFY
- If defined, the content of the flash (destination) is compared
- against the source after the write operation. An error message
- will be printed when the contents are not identical.
- Please note that this option is useless in nearly all cases,
- since such flash programming errors usually are detected earlier
- while unprotecting/erasing/programming. Please only enable
- this option if you really know what you are doing.

- CONFIG_ENV_FLAGS_LIST_DEFAULT
- CONFIG_ENV_FLAGS_LIST_STATIC
Enable validation of the values given to environment variables when
