Currently, some linker scripts are found by common code in config.mk. Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is sometimes in arch config.mk and sometimes in board config.mk. Some are found using an arch-specific rule for looking in CPUDIR, etc. Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds. Replace all of this -- except for a handful of boards that are actually selecting a linker script in a unique way -- with centralized ldscript finding. If board code specifies LDSCRIPT, that will be used. Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used. If neither of these are specified, then the central config.mk will check for the existence of the following, in order: $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds $(TOPDIR)/$(CPUDIR)/u-boot.lds Some boards (sc3, cm5200, munices) provided their own u-boot.lds that were dead code, because they were overridden by a CPUDIR u-boot.lds under the old powerpc rules. These boards' own u-boot.lds have bitrotted and no longer work -- these lds files have been removed. Signed-off-by: Scott Wood <scottwood@freescale.com> Tested-by: Graeme Russ <graeme.russ@gmail.com>
