Subject: [PATCH] ath79: port cybertan_part from ar71xx
|
|
|
|
|
|
|
|
|
|
This patch ports the cybertan_part code from ar71xx and converts the
|
|
|
|
|
driver to a DT-supported mtd parser. As a result, it will no longer
|
|
|
|
|
add the u-boot, nvram and art partitions, which were never part of
|
|
|
|
|
the special Cybertan header.
|
|
|
|
|
|
|
|
|
|
Instead these partitions have to be specified in the DT, which has the
|
|
|
|
|
upside of making it possible to add properties (i.e.: read-only), labels
|
|
|
|
|
and references to these important partitions.
