This patch adds essential components for generation of the contents of the linker section that is used by the linker-generated array. All of the contents is held in a separate file, u-boot.lst, which is generated at runtime just before U-Boot is linked. The purpose of this code is to especially generate the appropriate boundary symbols around each subsection in the section carrying the linker-generated arrays. Obviously, the interim linker code for actual placement of the variables into the section is generated too. The generated file, u-boot.lst, is included into u-boot.lds via the linker INCLUDE directive in u-boot.lds . Adjustments are made in the Makefile and spl/Makefile so that the u-boot.lds and u-boot-spl.lds depend on their respective .lst files.
