The driver for the wifi adapter is brcmfmac. It is compiled as a module 
and loaded via /etc/modules.
the driver depends on the modules brcmutil and cfg80211, which are auto 
loaded.

my user space is debian unstable. The kernel is cross compiled on my 
x86-64 laptop with gcc 5.4.1

i use my own kernel configuration without an initial ramdisk. mmc, usb & 
ext4 drivers are compiled into the kernel

kernel & dtb are loaded by u-boot from mmcblk2p1 (sd-card)

the drive for the kernel is sda2 (sd-card inside of a usb card reader).

here is the filtered (mmc|brcmfmac) syslog output when only patches 1 & 
2 are applied
