Revision 6d297540f75d759489054e8b07932208fc4db2cb authored by Rahul Lakkireddy on 11 June 2021, 06:47:47 UTC, committed by David S. Miller on 11 June 2021, 18:15:00 UTC 
cxgb4: halt chip before flashing PHY firmware image
 
When using firmware-assisted PHY firmware image write to flash,
halt the chip before beginning the flash write operation to allow
the running firmware to store the image persistently. Otherwise,
the running firmware will only store the PHY image in local on-chip
RAM, which will be lost after next reset.
