Description:

Patch# 1.54fw: 
 Root Cause: In HPS first mode, when the HPS-EMIF is configured as x72 and shares the same I/O bank with fabric EMIF, repeated core reconfigurations can cause the fabric EMIF to enter an incorrect reset state. As a result, the EMIF calibration firmware may wait indefinitely.
Fix: The EMIF calibration firmware was updated to detect whether the fabric EMIF is placed in the HPS-EMIF IO bank and, upon detecting core reconfiguration, place fabric EMIF into proper reset state.
JIRA reference: QS-16011 



Patch# 1.45fw: 
 Issue FPGA 1st with HPS and cold reset using external pin in loop test resulting in HPS boot up delayed by 16min.
It was fixed by resetting the flash device before starting calibration sequence.
[HSD#15018562361/QS-16155] 

Patch# 1.33fw: 
 Fixed race condition in handling SHA isr and resumption of FPGA data blocks.Drain DMA post a configuration/PR to flush out left over data if any.
Bug for tracking [15018400374] 

Patch# 1.30: 
 This Patch is to resolve Quartus_PFG SOF error while generating core.rbf & Hps.rbf with secure boot enabled 

Patch# 1.15fw: 
 The Safe SEU error injection mailbox command is a new featured added in 25.3. Patching the feature  which can be used instead of offline FID tool to inject SEU error from HPS.
