I just wonder if you wanted to apply your patch for 85xx board.:) Haiying ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

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? > CPUDIR is defined in config.mk, I tried it for 85xx/p1 boards and it > worked. 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.

Then 85xx boards still need to get the lds from board/$(BOARDIR)/config.mk.

Did you try it out? CPUDIR is defined in config.mk, I tried it for 85xx/p1 boards and it worked. Haiying ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
