* The ADS GCPlus Linux boot ROM loads U-Boot into RAM at 0xc0200000.
* We don't actually init RAM in this case since we're using U-Boot as
* an secondary boot loader during Linux kernel development and testing,
* e.g. bootp/tftp download of the kernel is a far more convenient
* when testing new kernels on this target. However the ADS GCPlus Linux
* boot ROM leaves the MMU enabled when it passes control to U-Boot. So
* we use lowlevel_init (!CONFIG_SKIP_LOWLEVEL_INIT) to remedy that problem.
