OMAP hwmod layer does the reset of the IPs in early code so that we have SOC in sane state. To do the soft-reset, it needs to ioremap() the ip address space to be able to write to sysconfig registers.
But there are few hwmod which doesn't have sysconfig registers and hence no need to ioremap() them in early init code. So this patch makes prevet calling the _init_mpu_rt_base() conditional based on sysc availability.
