[PATCH 0/3] ASoC: SOF: Intel: Fix IMR boot race caused by early core booting

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

Hi,

After the revisited IMR sequence patch
2a68ff846164 ("ASoC: SOF: Intel: hda: Revisit IMR boot sequence")

we have started to see random boot issues manifesting in ghost reply messages from
the DSP for a never sent message.
It turned out that an earlier commit:
d416519982cb ("ASoC: SOF: hda: don't use the core op for power up/power down")

replaced the core power up step with a full blown core power up + enable call.
The result was that we have booted the core before we would place the message
to the ROM code and based on luck and timing it got received by the (IMR) booted
firmware or in between ROM and firmware boot.

Mark, can you queue this series for 5.19 as the 2a68ff846164 is in rc1 to make
sure that we fix this random issue?

Regards,
Peter
