We have a kind of hierarchy
when arch/$(SRCARCH)/configs has sub-directories.
For example,

$ make ARCH=powerpc help
[ snip ]
storcenter_defconfig - Build for storcenter
tqm8xx_defconfig - Build for tqm8xx
wii_defconfig - Build for wii

help-40x - Show 40x-specific targets
help-44x - Show 44x-specific targets
help-52xx - Show 52xx-specific targets
help-83xx - Show 83xx-specific targets
help-85xx - Show 85xx-specific targets
help-boards - Show all of the above




I think your suggestion is, to keep the top "make help" as-is
and add new targets to display subsets.


All targets you can run from the top-level
must be described in "make help".

Maybe like this?

confighelp - Show only configuration targets
dochelp - Show only documentation targets


I feel a bit cumbersome, but I will probably accept it
if people think it is useful.
