ddr4: add DDR4 compilation flag to U-Boot build chain
The ddr4 pre-compiled libraries are attached by default to binary header,
under tools/marvell/bin_hdr/src_ddr/lib/ddr4_training_a38xsub.lib.
Unless stated otherise, the libraray will be used as part of the compilation flow.
- This patch add a new flag to U-Boot's root Makefile, to indicate DDR4 internal
sources compilation (fresh compilation of the above lib file)
- The flag is passed from U-Boot to binary header compilation.
- Accordingly, the sources under tools/marvell/bin_hdr/src_ddr/ddr3libv2/src/Driver/ddr4
are re-compiled, and the lib file is re-generated.
- To enable DDR4 sources compilation, add '-m 4 -d 4' to build.pl arguements.
(example: ./build.pl -b armada_38x -f spi -m 4 -d 4 )
