[U-Boot,2/4] arm64: xilinx: Move firmware functions from platform to driver

Message ID 7a294f10532b5b1a78e4700a4acc2f346e7a8c63.1570199266.git.michal.simek@xilinx.com

Commit Message

Michal Simek Oct. 4, 2019, 2:27 p.m. UTC
versal_pm_request() and invoke_smc() are almost the same. Only one
difference is that versal_pm_request is adding PM_SIP_SVC offset to api_id.
The patch is moving platform implementation to firmware driver code for
synchronization.

Not stated in the log message, but this check does not exist in current
invoke_smc(). It's useful to check as it avoids a big explosion in case
invoke_smc is called in the wrong context.

But, if possible, it would be good to emit an error here, or the failure
would be silent. Does this look correct?
But that would be another patch, so:

As you see it is a merge of that two functions together.

We can add debug message. It can't hurt.
