With this dependency the symbol EFI_EBBR_2_0_CONFORMANCE is superfluous.
Can we add EFI_EBBR_2_0_CONFORMANCE unconditionally or are there
relevant configuration flags in U-Boot that must be enabled to claim
EBBR 2.0 compliance? E.g.
* CONFIG_CMD_BOOTEFI_BOOTMGR
* CONFIG_EFI_GET_TIME
* CONFIG_EFI_CAPSULE_FIRMWARE_MANAGEMENT
Best regards
