hw_data_init() is called before relocation to initialise hardware data. Since ctrl is initialized to OMAP_SRAM_SCRATCH_SYS_CTRL in arch/arm/mach-omap2/am33xx/hw_data.c, the pointer *ctrl will not be updated during relocation and will hold a stale value.
Therefore call hw_data_init() again after relocation to reinitialize *ctrl.
