[PATCH v4 0/2] ath11k: add handler for board-2.bin without variant and read SMBIOS

[Wen Gong]

v4: 
   1. add helper function ath11k_core_create_fallback_board_name()
   2. rebased to ath.git ath-202112071521

v3:
   1. add patch "ath11k: add fallback board name without variant while searching board-2.bin"
   2. reabsed to latest ath.git master ath-202111221436

v2: rebased to latest ath.git master ath-202111170737

When it does not have matched board name with variant in board-2.bin,
ath11k will fallback to search without variant.

Also read the variant from SMBIOS.

  ath11k: add fallback board name without variant while searching
    board-2.bin
  ath11k: add read variant from SMBIOS for download board data

[PATCH v4 1/2] ath11k: add fallback board name without variant while searching board-2.bin

[Wen Gong]

Sometimes it has a variant value which read from DT or SMBIOS by
ath11k, and meanwhile it does not have the matched board name in
board-2.bin, then it will failed at boot up phase.

Add fallback board name which removed variant value and search again
in board-2.bin when failed with variant and try to load the board
data again to increase boot up success rate.

On Dell XPS 13 9310 I see a new warning when testing the pending branch:

[    2.471334] ath11k_pci 0000:72:00.0: chip_id 0x0 chip_family 0xb board_id 0xff soc_id 0xffffffff

[    2.513436] ath11k_pci 0000:72:00.0: leaving PCI ASPM disabled to avoid MHI M2 problems

I suspect (but not sure!) it comes from this patchset.

Patch set to Changes Requested.

On Dell XPS 13 9310 I see a new warning when testing the pending branch:

[    2.471334] ath11k_pci 0000:72:00.0: chip_id 0x0 chip_family 0xb board_id 0xff soc_id 0xffffffff
[    2.471339] ath11k_pci 0000:72:00.0: fw_version 0x101c06cc fw_build_timestamp 2020-06-24 19:50 fw_build_id 
[    2.471761] ath11k_pci 0000:72:00.0: failed to fetch board data for bus=pci,qmi-chip-id=0,qmi-board-id=255,variant=DE_1901 from ath11k/QCA6390/hw2.0/board-2.bin
[    2.513436] ath11k_pci 0000:72:00.0: leaving PCI ASPM disabled to avoid MHI M2 problems

I suspect (but not sure!) it comes from this patchset.

Patch set to Changes Requested.
