Structure of this binary (Example for the cam_enc_4xx board with a NAND
page size = 0x800):
-offset : 0x00000 | 0x800 | 0x3800

- Header | code |
+offset : 0x00000 | 0x800 | 0x3800

The NAND layout looks for example like this:
(Example for the cam_enc_4xx board with a NAND page size = 0x800, block
size = 0x20000 and CONFIG_SYS_NROF_UBL_HEADER 5):
-offset : 0x80000 | 0xa0000 | 0xa3000

If the cpu starts in NAND boot mode, it checks the UBL descriptor
starting with block 1 (page 0). When a valid UBL signature is found,
Once the user-specified start-up conditions are set, the RBL copies the
nand_spl into ARM internal RAM, starting at address 0x0000: 0020.

The nand_spl code itself now does necessary intializations, and at least,
copies the u-boot code from NAND into RAM, and jumps to it ...
If you look at drivers/usb/eth/asix.c you will see this line within the
supported device list, so we know this adapter is supported.

If your adapter is not listed there is a still a chance that it will
work. Try looking up the manufacturer of the chip inside your adapter.
support USB with CONFIG_CMD_USB enabled and working. You will need to
add some config settings to your board header file:
-#define CONFIG_USB_HOST_ETHER /* Enable USB Ethernet adapters */
-#define CONFIG_USB_ETHER_ASIX /* Asix, or whatever driver(s) you want */
+#define CONFIG_USB_HOST_ETHER /* Enable USB Ethernet adapters */
+#define CONFIG_USB_ETHER_ASIX /* Asix, or whatever driver(s) you want */
As with built-in networking, you will also want to enable some network
commands, for example:
as well as the default file to load when a 'bootp' command is issued.
All of these can be obtained from the bootp server if not set.
