Subject: [PATCH] ath10k: Add support to provide higher range mem chunks in wmi init command
Git-commit: 40f4ef5e92326ab127bdeb6f024855c8c91de608
Patch-mainline: v5.5-rc1
References: jsc#SLE-13430
With the current implementation of wmi init command,
there is no provision for the host driver to provide mem
chunks addresses with more than 32-bit, to the firmware.
WCN3990 is a 35-bit target and can accept mem chunks addresses
which are above 32-bit.
If firmware supports address range more than 32 bit, it
advertises the support by setting the WMI_SERVICE_EXTEND_ADDRESS
service. Based on this service fill the upper bits of paddr while
providing the mem chunks in the wmi init command.
Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1
