ARM: 8458/1: bL_switcher: add GIC dependency
It is not possible to build the bL_switcher code if the GIC driver is disabled, because it relies on calling into some gic specific interfaces, and that would result in this build error: arch/arm/common/built-in.o: In function `bL_switch_to': :(.text+0x1230): undefined reference to `gic_get_sgir_physaddr' :(.text+0x1244): undefined reference to `gic_send_sgi' :(.text+0x1268): undefined reference to `gic_migrate_target' arch/arm/common/built-in.o: In function `bL_switcher_enable.part.4': :(.text.unlikely+0x2f8): undefined reference to `gic_get_cpu_id' This adds a Kconfig dependency to ensure we only build the big-little switcher if the GIC driver is present as well. Almost all ARMv7 platforms come with a GIC anyway, but it is possible to build a kernel that disables all platforms.
