At present fdt blob or argument address being passed to kernel is fixed at compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from different media like nand, nor flash are copied to the address pointed by the macro. The problem is, it makes args/fdt blob compulsory to copy which is not required in cases like for NOR Flash. This patch removes this limitation. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
