[PATCH v2 0/2]EDAC/altera: Check previous DDR DBE during driver probe

[niravkumar . l . rabara]

From: Niravkumar L Rabara <niravkumar.l.rabara@xxxxxxxxx>

Starting from SoCFPGA Agilex7, new SDM mailbox command is introduced to
read Single Event Upset Error information, SEU can detect 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.

changelog v2:
* Updated command ID for SEU error
