Hi os user,

Hi All,

In top-level Makefile, there are some tricks to support more config items. For example,

Lite5200_config \ Lite5200_LOWBOOT_config \ Lite5200_LOWBOOT08_config \ icecube_5200_config \ icecube_5200_LOWBOOT_config \ icecube_5200_LOWBOOT08_config \ icecube_5200_DDR_config \ icecube_5200_DDR_LOWBOOT_config \ icecube_5200_DDR_LOWBOOT08_config: unconfig @mkdir -p $(obj)include @mkdir -p $(obj)board/icecube @[ -z "$(findstring LOWBOOT_,$@)" ] || \ if [ "$(findstring DDR,$@)" ] ; \ then echo "TEXT_BASE = 0xFF800000" >$(obj)board/icecube/config.tmp ; \ else echo "TEXT_BASE = 0xFF000000" >$(obj)board/icecube/config.tmp ; \ fi @[ -z "$(findstring LOWBOOT08,$@)" ] || \ echo "TEXT_BASE = 0xFF800000" >$(obj)board/icecube/config.tmp @[ -z "$(findstring DDR,$@)" ] || \ echo "#define CONFIG_MPC5200_DDR" >>$(obj)include/config.h @$(MKCONFIG) -n $@ -a IceCube powerpc mpc5xxx icecube

If we want to apply this kind of trick to current boards.cfg, what should we do? Add a lot of items in boards.cfg?

That's the idea - one line per supported configuration. Somehow we need something like the "-t" trick of mkconfig though and as yet we have no working solution for this.

Ideally the configuration name (1st column) will be split into a base configuration plus options which result in individual defines tha can be used in the code. I think Wolfgang started to work on this, so I especially ping him on this one.

Cheers Detlev
