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,
|
||||||
|
which has a different number of maximum PCI devices.

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.
