Current PFE firmware access spi-nor memory directly. New spi-mem
framework does not support direct memory access. So, let's use
spi_flash_read API to access memory instead of directly using it.

v3:
-Replace ret with 0 if flash probe fails
v2:
-Add return error code
-Some changes in displayed log

No again. It seems like you're not getting what I'm trying to tell you, 
so it would be better to just ask back instead of posting new versions.

pfe_spi_flash_init() should return an error code in case the probe of 
the SPI flash failed. An error code is a negative value like for example 
-ENODEV to report that the device is not available to the calling function.

Thanks Frieder for providing the info.
I will return -ENODEV here instead of 0.

I think -EIO should also be returned here as pfe functionality will fail if data is not read.
Please confirm the same if error code is correct/required. I will update this in next version.

Thanks

No, I don't think it's a good idea to return an error code here. You 
already get an error code back from spi_flash_read() if it fails and you 
pass this error to the caller at the end of the function, which should 
be sufficient.

Also returning here would require to add a call to spi_flash_free() first.
