Atish Patra 66b1205bc5 RISC-V: Copy the fdt in dram instead of ROM 
Currently, the fdt is copied to the ROM after the reset vector. The firmware
has to copy it to DRAM. Instead of this, directly copy the device tree to a
pre-computed dram address. The device tree load address should be as far as
possible from kernel and initrd images. That's why it is kept at the end of
the DRAM or 4GB whichever is lesser.
