[V2] ath10k-firmware: QCA9888 hw2.0: Add BDF for Linksys EA8300 [2/2]

[Christian Lamparter]

From: Jeff Kletsky <lede at allycomm.com>

This is a IPQ4019-based device with a PCI-attached QCA9888
supplying a third radio on 5 GHz. The OEM's firmware and source
suggest that this device is "based on Qualcomm AP DK07.1-c1"

Linksys ships four market-specific variants of this device, notated as
-AH, -EU, (no suffix), and -CA. They supply four sets of pre-cal board
files in their firmware, AH, EU, FCC, and IC. The corresponding files
differ from each other, and appear to provide different parameters in
the different regions. The OEM firmware copies the appropriate set of
files into place based on examining the SKU of the device at boot.

These board files may be obtained from extraction of the OEM firmware
Ver. 1.1.4.191539, Latest Date: 11/8/2018, 49.0 MB

and/or from a running device. There does not appear to be a difference
in the board files between the two firmware versions.

DTS for the EA8300 under OpenWrt expects that the variant be encoded
as, for example, linksys-ea8300-fcc, with the lower-cased suffix
indicating the OEM's regional code, or -fcc.

Two similar messages will be sent, one for each chipset, as per the directions.


The files selected and their original names and organization include:

         27d9dfe1e86c3befe808f89dd3cd105b  OEM/QCA9888/IC/boardData_2_0_QCA9888_5G_Y9690_SBS_HB.bin
         7f2f0de6c0fb2df1d642895d8233d3ef  OEM/QCA9888/EU/boardData_2_0_QCA9888_5G_Y9690_SBS_HB.bin
         62049f88a498e51870973143e376e7af  OEM/QCA9888/FCC/boardData_2_0_QCA9888_5G_Y9690_SBS_HB.bin
         27d71485fc4987bc1c11b7744c373b59  OEM/QCA9888/AH/boardData_2_0_QCA9888_5G_Y9690_SBS_HB.bin

The files were renamed as follows:

         for JD in AH EU FCC IC ; do
             jd=$(echo "$JD" | tr 'A-Z' 'a-z')
             cp -vp OEM/QCA9888/${JD}/boardData_2_0_QCA9888_5G_Y9690_SBS_HB.bin \
	    ${dest}/bus=pci,bmi-chip-id=0,bmi-board-id=23,variant=linksys-ea8300-${jd}
         done


Renamed board files are individually attached to QCA9888 messages.
