Control State for SPI boot flash selection:
(These settings are stored in EEPROM and applied (to logic) each time the IPMI controller
detects power-on)
00h = Standard SPI boot flash is selected (default)
01h = Recovery SPI boot flash is selected
Please note that this selection may be forcibly overridden either by the DIP Switch SW3,
switch 2 (refer to the AM4022 User Guide, Table 4-3).
To be able to change the SPI boot flash selection via the Set Control State command, the
recovery SPI boot flash must not be previously selected.
In case of a failed boot process from the standard SPI boot flash, the IPMI controller will
select the recovery SPI boot flash and boot the board again.
In case of a boot failure from the recovery SPI boot flash, the board locks up.
Refer to Chapter 8, uEFI BIOS Failover Control - Automatic SPI Boot Flash Selection, for
further information.
