2. This file can have empty lines and lines starting with "#" as first
character to put comments
3. This file can have configuration command lines as mentioned below,
support USB with CONFIG_CMD_USB enabled and working. You will need to
add some config settings to your board header file:
+#define CONFIG_CMD_USB /* the 'usb' interactive command */
#define CONFIG_USB_HOST_ETHER /* Enable USB Ethernet adapters */
-#define CONFIG_USB_ETHER_ASIX /* Asix, or whatever driver(s) you want */
+
+and one or more of the following for individual adapter hardware:
+
+#define CONFIG_USB_ETHER_ASIX
+#define CONFIG_USB_ETHER_MCS7830
+#define CONFIG_USB_ETHER_SMSC95XX
As with built-in networking, you will also want to enable some network
commands, for example:
You can also set the default IP address of your board and the server
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.
+However note that encoding these individual network settings into a
+common exectuable is discouraged, as it leads to potential conflicts,
+and all the parameters can either get stored in the board's external
+environment, or get obtained from the bootp server if not set.
#define CONFIG_IPADDR 10.0.0.2 (replace with your value)
#define CONFIG_SERVERIP 10.0.0.1 (replace with your value)

+ *
+ * This emulation includes the following:
+ *
+ * 1. Emulation of the keyboard, by converting keypresses received from SDL
+ * into key scan data, passed back from the EC as key scan messages. The
+ * key layout is read from the device tree.
+ *
+ * 2. Emulation of vboot context - so this can be read/written as required.
+ *
+ * 3. Save/restore of EC state, so that the vboot context, flash memory
+ * contents and current image can be preserved across boots. This is important
+ * since the EC is supposed to continue running even if the AP resets.
+ *
+ * 4. Some event support, in particular allowing Escape to be pressed on boot
+ * to enter recovery mode. The EC passes this to U-Boot through the normal
+ * event message.
+ *
+ * 5. Flash read/write/erase support, so that software sync works. The
+ * protect messages are supported but no protection is implemented.
+ *
+ * 6. Hashing of the EC image, again to support software sync.
+ *
+ * Other features can be added, although a better path is probably to link
+ * the EC image in with U-Boot (Vic has demonstrated a prototype for this).
