From 5bf5250e9d1555aa388a810213fd85106a60388e Mon Sep 17 00:00:00 2001 From: Vikas Manocha Date: Fri, 7 Apr 2017 15:38:13 -0700 Subject: spl: make image arg or fdt blob address reconfigurable 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.
