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
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. Fixes: 4ee339e1e92a ("cxgb4: add support to flash PHY image") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
