Oops, sorry. I missed that one, even though I was looking for it :-(

No, not really. But actually I was just cleaning up probems where ran
into them, not trying to perform a more general cleanup [*].
The situation is that the relevant 85xx boards appeare to have their
own config.mk files which explicitly set LDSCRIPT to the value they
need (which is indeed different from the default that gets set up ib
arch/powerpc/config.mk:
arch/powerpc/config.mk: LDSCRIPT :=
$(SRCTREE)/$(CONFIG_BOARDDIR)/u-boot-nand.lds
board/freescale/mpc8536ds/config.mk: LDSCRIPT :=
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds
board/freescale/mpc8569mds/config.mk: LDSCRIPT :=
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds
board/freescale/p1_p2_rdb/config.mk: LDSCRIPT :=
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds
So it seems my patches do not have any impact on the building of 85xx
systems. Or am I missing something?

OK, I'll remember this for the next optimization.
[*] There is more that can be done for ontimization: actually many of
the PPC u-boot.lds files are (except for white space, indentation
and tiny irrelevant details) identical. I intend to use a single,
common linker script for all these cases, which will allow to
remove dozens of more or less identical files.
But I want to have a stable code base first.
Best regards,
Wolfgang Denk
