I believe I understand what you are trying to achieve here, which is to have an identical defconfig file that you can share between a big-endian and little-endian kernel? Is not this something better left to a build system which understands what config fragments are in general? Since we seem to have support for fragments now with kvm and friends, having this does not seem to be a big stretch though. > > Signed-off-by: Scott Branden <sbran...@broadcom.com> > --- > kernel/configs/be.config | 1 + > kernel/configs/le.config | 1 + > scripts/kconfig/Makefile | 10 ++++++++++ > 3 files changed, 12 insertions(+) > create mode 100644 kernel/configs/be.config > create mode 100644 kernel/configs/le.config > > diff --git a/kernel/configs/be.config b/kernel/configs/be.config > new file mode 100644 > index 0000000..c5cdc99 > --- /dev/null > +++ b/kernel/configs/be.config > @@ -0,0 +1 @@ > +CONFIG_CPU_BIG_ENDIAN=y > diff --git a/kernel/configs/le.config b/kernel/configs/le.config > new file mode 100644 > index 0000000..be479cf > --- /dev/null > +++ b/kernel/configs/le.config > @@ -0,0 +1 @@ > +# CONFIG_CPU_BIG_ENDIAN is not set > diff --git a/scripts/kconfig/Makefile b/scripts/kconfig/Makefile > index d79cba4..2e8007e 100644 > --- a/scripts/kconfig/Makefile > +++ b/scripts/kconfig/Makefile > @@ -126,6 +126,14 @@ PHONY += tinyconfig > tinyconfig: > $(Q)$(MAKE) -f $(srctree)/Makefile allnoconfig tiny.config > > +PHONY += beconfig > +beconfig: be.config > + @: > + > +PHONY += leconfig > +leconfig: le.config > + @: > + > # Help text used by make help > help: > @echo ' config - Update current config utilising a > line-oriented program' > @@ -151,6 +159,8 @@ help: > @echo ' kvmconfig - Enable additional options for kvm guest > kernel support' > @echo ' xenconfig - Enable additional options for xen dom0 and > guest kernel support' > @echo ' tinyconfig - Configure the tiniest possible kernel' > + @echo ' beconfig - Update current config to use big endian CPU' > + @echo ' leconfig - Update current config to use little endian > CPU' > > # lxdialog stuff > check-lxdialog := $(srctree)/$(src)/lxdialog/check-lxdialog.sh > -- Florian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
