IPQ4019 Firmware: board-2.bin vs board.bin

[Christian Lamparter]

Hello,

I've acquired a IPQ4019 Router (Asus RT-AC58U). And It has a IPQ4019-SoC.
I'm currently in the process of porting it to LEDE. I can report that the
router is booting and I got the ath10k to work with 4.8.8 +
LEDE's compat-wireless (2016-10-08-1).

Now, I ran across a small discrepancy with the provided firmware for
the IPQ4019. From the ath10k's driver prospective it seems that the
board-2.bin provided on github[0] has the wrong filename:

ath10k_ahb a000000.wifi: Direct firmware load for ath10k/pre-cal-ahb-a000000.wifi.bin failed with error -2
ath10k_ahb a000000.wifi: Falling back to user helper

ath10k_ahb a000000.wifi: could not probe fw (-11)

Now, If I rename board-2.bin to board.bin it works fine and the device initializes
successfully (and seems to work too):

ath10k_ahb a000000.wifi: Direct firmware load for ath10k/pre-cal-ahb-a000000.wifi.bin failed with error -2

What's up with the board-2.bin name? Kalle, can you rename it or
should ath10k look for board-2.bin instead?

Christian
