+This patch adds support for the Gateworks Avila Network Platform in
+a separate set of setup files to the IXDP425. This is necessary now
+that a driver for the Avila CF card slot is available. It also adds
+support for a minor variant on the Avila board known as the Loft,

+Add EEPROM notifiers
+
+These help board level code by allowing a callback when EEPROMs are
+loaded, this permits system level configuration to be loaded from the
+EEPROM.  This is particularly useful when the ethernet MAC ids are
+stored in EEPROM and when the ethernet hardware is generic (so it
+has no board level knowledge), then the MACs can be loaded into
+the 'maclist' code and read out by the ethernet config.
