[Mesh] Illustrated walkthrough for flashing "raw" Aruba AP175 boards

Hi all, I'm sharing this info in case other communities outside of Newport Wireless Mesh may find it useful. The Aruba AP175 is a high-power, stable, electrically protected outdoor access point that I recently ported to OpenWrt, and I hope other communities might get good use out of it. It's old hardware, but very available, and for multiple reasons will likely enjoy long-term supportability (ath9k, 128M RAM / 16M NOR). Newport Wireless Mesh will continue to use Aruba AP175s that I have personally flashed. Van Tech Corner (THANK YOU, VAN!) did a video explaining how, given an Aruba AP175 in unknown state, we can use a Raspberry Pi or CH341A and 16-pin Pomona chip clip to reflash the Aruba AP175 to a custom U-Boot compatible with OpenWrt 23 and onwards: https://www.youtube.com/watch?v=-SikTSsRvQE Martin
