I assume most ArchLinux ARM users are techier than the average user, but I have a suggestion that might make the boards a little easier to navigate.
When the recent Broadcom category was added to the Hardware/ARMv7 devices category, the description for the Broadcom forum reads “Raspberry Pi 2” instead of the same standard in the other forums which is “This forum is for supported devices using an ARMv7 XXXX SoC” where XXXX is the SoC manufacture.
I don’t know if it was a mistake to add “Raspberry Pi 2” to the Broadcom hardware forum description, but I can see having the actual device name, which is similar to how the Platforms are organized on the main page, may make it easier to locate an applicable hardware forum.
