[PATCH 0/5] ath25: return back with 5.4 kernel support

[Sergey Ryazanov]

This series returns back ath25 target and switches it to 5.4 kernel.

Discussion in the mailing list revealed that this target still has
active users and some boards still have enough Flash/RAM. We are able to
upgrade target to a fresh kernel and there are no objection against
a target recovery. So, lets return the ath25 target back for at least
the next release circle.

Compile- and run-tested with the following boards:
* D-Link DIR-300 A1 (AR2317)
* D-Link DWL-2100AP (AR2313)

Partially tested with Fonera FON2201 (AR2315 based). My single board has
misteriously bricked during a routine sysupgrade (power issue?). But
Ethernet and Wi-Fi interfaces were tested and work as expected.
