Hi,
I've just added support for the COMFAST CF-E313AC, an outdoor wireless
CPE with two Ethernet ports and a 802.11ac radio (see patch below).
Everything is working fine but I've got two issues for which I'd like to
get some advise:
1) target/linux/ath79/base-files/etc/hotplug.d/firmware/11-ath10k-caldata
I had to add "rm /lib/firmware/ath10k/QCA9888/hw2.0/board-2.bin", since
the driver tries to board-2.bin (the default calibration data from the
firmware package) first and, when that file is not found, falls back to
board.bin (the calibration data read from the flash).
I haven't seen this on any other device, so I guess there must be a more
elegant way to deal with it. Any idea?
2) target/linux/ath79/dts/qca9531_comfast_cf-e313ac.dts
The device is equipped with a "w25q128" flash chip (16384 Kbytes) but the
stock firmware image only used half of it (nvram partition finishes at
0x000000800000, i.e., 8192 Kbytes):
*** stock firmware bootlog ***

[ 0.790000] 0x000000020000-0x0000007e0000 : "firmware"
[...]
Is there a way to use the remaining half of the flash?
Any comments regarding these or other issues will be highly appreciated.
Thanks!
