[V2] ath10k-firmware: QCA4019 hw1.0: Add BDF for Linksys EA8300 [1/2]

[Christian Lamparter]

From: Jeff Kletsky <lede at allycomm.com>

This is a QCA4019-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.


The files selected and their original names and organization include:

          435d236890521515feffc834218ca594  OEM/IPQ4019/IC/boardData_1_0_IPQ4019_DK04_5G.bin

          d6d7ed00db985b4d8c48ccc3fe10fa87  OEM/IPQ4019/EU/boardData_1_0_IPQ4019_DK04_5G.bin
          5cef8208a0345c1469494e44e1f370f1  OEM/IPQ4019/EU/boardData_1_0_IPQ4019_DK04_2G.bin
          0e820f5946b5773ad9f4a74809c05b79  OEM/IPQ4019/FCC/boardData_1_0_IPQ4019_DK04_5G.bin
          057ed5528e360197c2239796710cb61c  OEM/IPQ4019/FCC/boardData_1_0_IPQ4019_DK04_2G.bin
          0171919a4576199ae88e8831f72c03fe  OEM/IPQ4019/AH/boardData_1_0_IPQ4019_DK04_5G.bin
          a8e23769dc98da97b6c70a4f601ffca8  OEM/IPQ4019/AH/boardData_1_0_IPQ4019_DK04_2G.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/IPQ4019/${JD}/boardData_1_0_IPQ4019_DK04_2G.bin \
	    ${dest}/bus=ahb,bmi-chip-id=0,bmi-board-id=20,variant=linksys-ea8300-${jd}
              cp -vp OEM/IPQ4019/${JD}/boardData_1_0_IPQ4019_DK04_5G.bin \
	    ${dest}/bus=ahb,bmi-chip-id=0,bmi-board-id=21,variant=linksys-ea8300-${jd}
          done


Renamed board files are individually attached to the IPQ4019
messages. dmesg excerpts are from the device running OpenWrt with
locally crafted, aggregate board files.
