addresses to the currently stand-by U-Boot bank, while
protect off 1:252-258
addresses the currently active U-Boot bank.
The currently stand-by U-boot bank is always mapped to the start address 0xE2000000,
while the currently active U-boot bank is always mapped to 0xE0000000.
If you wish to set a particular U-boot bank into the active state, then you need to set the
System Boot Options Parameter #96 (bit 0) appropriately and reboot. If this bit is set to 0,
then U-boot bank 1 will be active after the next reboot. If the bit is set to 1, then U-boot bank
2 will be active. Note that depending on the blade’s IPMI firmware version, the switch
between the U-boot banks may be effective immediately.
