As of gcc 5.2.1 for Thumb-1, it is not possible any more to assign gd from C code, as gd is mapped to r9, and r9 may now be saved in the prolog sequence, and restored in the epilog sequence, of any C functions. Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().
