I can't get Alpine to detect the wireless interface at all. I suspect that this is a firmware issue, but how do I update the firmware on Raspberry Pi 3, where the fs is readonly?

I used a different computer and copied required firmware files as explained in wiki page "Raspberry pi 3 setting up WAP" or similar. Copy files where stated and reboot. You should have wlan available.

To be more exact, using parts of previous guide and the Raspberry Pi 3 - Configuring it as wireless access point -AP Mode guide - the steps to follow to make an installation work with wifi from initial boot are as follows:
1. Format SD, extract stuff onto it
2. Unsquash the /media/mmcblk0p1/boot/modloop-rpi2 to some temporary place (/tmp/ is used in this guide)
3. Copy brcmfmac43430-sdio.bin & brcmfmac43430-sdio.txt into /tmp/squashfs-root/modules/firmware/brcm/
4. Resquash the /tmp/squashfs-root/ to modloop-rpi2 then replace /media/mmcblk0p1/boot/modloop-rpi2
5. Boot and install as usual, during the setup-interfaces step it wlan0 should be present
