From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>
Starting from SoCFPGA Agilex7, new SDM mailbox command is introduced to read Single Event Update Error information, SEU detects both corrected and uncorrected error.
If the previous HPS reboot caused by the DDR double bit error, bit-31 is set high of boot scratch register 8. EDAC driver probe will check this bit status and sends the SMC command to Arm Trusted Firmware. Firmware will send mailbox command to SDM to get the SEU error information and pass it to EDAC driver, driver will print error count, sector address and error data for previous DDR DBE.
