What does luci display on other architectures?

"system": "Intel(R) Pentium(R) CPU G3258 @ 3.20GHz"

The information is drawn from ubus call system board - the system field.

The responsible code is found here:
https://lxr.openwrt.org/source/procd/system.c#L73

Seems another case for Hardware: needs to be added

What information should it display " "target": "bcm27xx/bcm2711",?

Was browsing the forums for rpi 4 and came up on this thread. According to this page:
https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md
Even though it's BCM2711 the kernel reports BCM2835 (Kernel 4.9 onwards). Just thought I'd share that info.
