This series fixes two problems on the Sophgo CV1800B/SG2002 Milk-V Duo boards.
Patch 1 fixes the fdtfile environment variable of the Milk-V Duo 256M. CONFIG_DEFAULT_DEVICE_TREE is a quoted string, so the quotes ended up in the environment. Patch 2 keeps U-Boot out of the memory reserved for the coprocessor firmware. The upstream devicetrees reserve the end of DRAM as a no-map region, but U-Boot relocates to ram_top, which is the end of DRAM, so it lands inside that region. This was tested on both Milk-V Duo 64M and 256M (CV1800B and SG2002).
