[partially SOLVED] no wifi with cubietruck on ARM Archlinux

[wsu]

Hi,

Yesterday I wanted to install Arch on my Cubietruck. Flashing a µ-SD card and starting the OS on CTK worked great, but I discovered that the WIFI device were not loaded. After some intense reflection, and understanding brcmfmac kernel module is responsable of the working condition of the Wifi, I understood this dmesg message could help me:

$this->bbcode_second_pass_code('', 'brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43362-sdio.txt failed with error -2')

this faulty firmware is located here:
$this->bbcode_second_pass_code('', '/lib/firmware/brcm')

My solution:
First, I made a backup of arch's original firmware, then I installed the firmware from a working ARMbian:
$this->bbcode_second_pass_code('', 'root@arch # mv /lib/firmware/brcm /lib/firmware/brcm.orig')
$this->bbcode_second_pass_code('', 'root@armbian # tar -cf - /lib/firmware/brcm | ssh root@arch "tar -xf -" ')

I had to reload impacted kernel modules with rmmod and modprobe, and all worked nice after that.

My question: I'm quite newbie with Arch so where can I report this problem so that developers can update this firmware for a working Arm Archlinux with Cubietruck?
