PQI Air Penのath79対応

以前、OpenWrtに対応させたのですが、ar71xxはath79に移行される事になったので、どこかで書き直さないといけないわけですがサボってました。
ar71xxは、今のkernelバージョンで終了の様子なので、ath79移行は今後OpenWrtで使えるようにするには必要なことになります。
とりあえず少し古いけど、手元の開発環境でパッチを書いてみた。
r7995-967d646_ath79_pqi-air-pen.patch


ath79対応してみたものの、恩恵を受けないですね。ar9330では正直あまりメリット無いですね。
Kernelでかくなってしまったし、Flash小さいからますますメリット無いですね。


起動ログ貼り付けておきますね。
とりあえず動作問題なさそうなので、最新にパッチ作って送りますかね。
