    Handle most LDSCRIPT setting centrally · 83b7e2a7

    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.
