openwrt: backport combination of dual-flash partitions
Backport two patches combining dual-flash layouts of OCEDO as well as UniFi AC boards. The two firmware partitions are already combined on OpenWrt master to prolong the life of these devices. It allows the device to store firmware images up to 14 MB compared to the previous 7 MB. The intention behind backporting these patches is to allow these devices to have a wide update path to firmware-versions requiring this extra space. Otherwise a device might not be able to install an upgrade which exceeds a single firmware-partition. For UniFi AC boards it should be noted that factory-installation will not be possible with an image exceeding a single firmware-partition. In this case, an older OpenWrt image that fits in a single partition and supports writing the enlarged partition space is required. Currently, this is not the case. As these devices are end-of-sale, this will become less of a concern over time. Signed-off-by: David Bauer <mail@david-bauer.net>

Subject: ath79: combine OCEDO dual firmware-partitions
|
||||
|
||||
In order to maximize the available space on OCEDO boards using a
|
||||
dual-image partition layout, combine the two OS partitions into a single
|
||||
partition.
|
||||
|
||||
This allows users to access more usable space for additional packages.
|
||||
|
||||
Don't limit the usable image size to the size of a single OS partition.
|
||||
The initial installation has to be done with an older version of OpenWrt
|
||||
in case the generated image exceeds the space of a single OS
|
||||
partition in the future.
