As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed.
We now implement the following hierarchy:
- Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file.
- If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_U_BOOT is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets use.
u-boot-nand.lds is not in board/$(BOARDDIR) for 85xx at least, it is in $(SRCTREE)/$(CPUDIR)/
- If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that.
should we use $(CPUDIR) instead of arch/powerpc/cpu/$(CPU)?
