The following diffs adds iwm(4) to the riscv64 kernel config.
I tested this with the following device:
iwm0 at pci5 dev 0 function 0 "Intel Dual Band Wireless-AC 9260" rev 0x29, intx
icarus$ ifconfig iwm0
iwm0: flags=808843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,AUTOCONF4> mtu 1500
lladdr bc:54:2f:cb:3b:21
index 2 priority 4 llprio 3
groups: wlan egress
media: IEEE802.11 autoselect (HT-MCS0 mode 11n)
status: active
ieee80211: nwid <My-SSID> chan 36 bssid 18:4b:0d:17:c0:ac 100% wpakey
wpaprotos wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp
inet 192.168.1.76 netmask 0xffffff00 broadcast 192.168.1.255
Patch and dmesg to follow. fw_update went fine and after enabling
debugging on the driver it doesn't seem to be throwing firmware errors
or anything like that. This is my only iwm(4) compatible device
unfortunately so I can't test with any others. This seems to be happily
passing packets.
