Subject: [PATCH] ath10k: Fix device boot error
Date:   Mon, 13 Sep 2021 20:50:48 +0300

From: Abinaya Kalaiselvan <akalaise@codeaurora.org>

mask value ATH10K_FW_CRASH_DUMP_RAM_DATA is not mandatory to get iram
mem layout. So introduced ath10k_coredump_get_hw_mem_layout to copy
hardware memory layout.

This fixes the below boot error:
[   17.468882] ath10k_pci 0000:06:00.0: failed to copy target iram contents: -12
[   17.513925] ath10k_pci 0000:06:00.0: could not init core (-12)
[   17.517635] ath10k_pci 0000:06:00.0: could not probe fw (-12)

Tested-on: QCA9984 X86 10.4-3.9.0.2-00139

Fixes: 9af7c32ceca8 ("ath10k: add target IRAM recovery feature support")
