Should look the same as in Linux (with overlay patches applied).

Relative file paths are looked up according to $global.firmware.path, which is initialized to /env/firmware by default. You can add extra paths there and if you are using bootloader spec, /lib/firmware on the partition containing the entries is temporarily prepended to the search path. The symbols in question are firmware_(set|get)_searchpath.
