Not sure if you're asking specifically about Tim's / octeontx's case
or in general, but see the ipq806x and ipq40xx "chromium" sub-targets.
The Google WiFi and the OnHub devices can boot from USB storage; and
this is the primary way to install OpenWrt on them. Because of kernel
config complaints, I made them separate sub-targets to include
USB_STORAGE drivers.
