This patch changes the dependency so that other arch like ARM64 can use ISCSI_IBFT as long as the arch supports ACPI. ibft_init() needs to use the global variable ibft_addr declared in iscsi_ibft_find.c. A #ifndef CONFIG_ISCSI_IBFT_FIND is needed to declare the variable if CONFIG_ISCSI_IBFT_FIND is not selected. Moving ibft_addr into the iscsi_ibft.c does not work because if ISCSI_IBFT is selected as a module, the arch/x86/kernel/setup.c won't be able to find the variable at compile time.
