We're inconsistent in spelling Arm/ARM. E.g.

https://doc.qt.io/qt-6/supported-platforms.html

uses both "Windows on ARM" ,and "Linux on Arm".

Checking https://www.arm.com/company/policies/trademarks/guidelines-trademarks, the original trademark owner wants to have it spelled Arm. This is also what e.g. Microsoft is using: https://learn.microsoft.com/en-us/windows/arm/overview

While at it, consider using the QDoc \tm command. This prevents accidental translations, and also adds an ® in the first occurence at each page.
