Add 256m memory profile

[proxer05]

https://github.com/bkspc/backspacewrt/commits/main/target/linux/qualcommax Based on mr7350 dtsi we should be able to boot ath11k mode 2 allowing stock devices to boot. Memory usage with dns recursor (unbound). Basic functionality without services like this should be possible(as on stock fw).

Do you mean that 256M of memory can also enable WiFi?

[proxer05]

Exactly. That's how Xiaomi and other OEMs are able to use 256mb dies.

Something changed from the time we talked for the first time? I tried once and I had oom after a while of using wifi.
