This patch adds support for QCA2066 firmware patch and NVM downloading. as the RF performance of QCA2066 SOC chip from different foundries may vary. Therefore we use different NVM to configure them based on board ID. Changes in v2 - optimize the function qca_generate_hsp_nvm_name - remove redundant debug code for function qca_read_fw_board_id Signed-off-by: Tim Jiang <quic_tjiang@quicinc.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
