[PATCH] ASoC: SOF: ipc4: Move window offset configuration earlier
With the added exception handling support if the firmware fails to boot up we are trying to do a panic dump from the telemetry slot. The slot offsets would have been configured only after receiving the FW_READY message which makes this panic dump unusable for early boot failures.
With IPC4 the DSP window offsets are at standard places unlike IPC3 where the offsets needs to be queried from the FW_READY message.
Move the offset configuration to sof_ipc4_init from the fw_ready handler.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
