Description: Bank0 U-boot version.
What is cienaCesModuleSwBank0UbootVersion?
This object reports the U-Boot bootloader version stored in boot bank 0 of the module. U-Boot is what runs before the kernel even loads, so knowing which version sits in this bank matters specifically when a bootloader-level upgrade is being planned, since a mismatched or outdated U-Boot version can sometimes fail to load a newer kernel correctly. For example, an older U-Boot version recorded here alongside a newer kernel in the same bank could explain a boot failure that a kernel-version check alone wouldn't reveal.
