ARM: 8454/1: OF implies OF_FLATTREE
On the ARM architecture, individual platforms select CONFIG_USE_OF if they need it, but all device tree code is keyed off CONFIG_OF. When building a platform without DT support and manually enabling CONFIG_OF, we now get a number of build errors, e.g. arch/arm/kernel/devtree.c: In function 'setup_machine_fdt': arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration] We could now try to separate the use case of booting from DT vs. the case of using the dynamic implementation, but that seems more complicated than it can gain us. This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little extra code when we just want the dynamic OF implementation, but that seems like a rather obscure case, and this version solves all CONFIG_OF related randconfig regressions.
