Just wanted to note that this isn't true for the 64r6el_defconfig &
32r2_defconfig (or similarly other variations of architecture revision &
endianness). They aren't files under arch/mips/configs/, instead these configs
are generated by merging a bunch of config fragments atop arch/mips/configs/
generic_defconfig. This allows us to have these minor variations on the base
generic_defconfig without duplicating its content & incurring the maintenance
headache of keeping them all in sync. For reference powerpc do similar things
to generate variations upon their real defconfigs.
If you do have a way to get 64r6el_defconfig & 32r2_defconfig included that
would be great, since more MIPS boards should be covered by these generic
configurations over the next few cycles.
Got it, thank you for the explanations! It's very helpful to get the
tips on what set of kconfigs should be included in the minimal test
coverage.
I'll add 64r6el_defconfig and 32r2_defconfig to the list.
It looks will merge several configs together:
wfg@inn ~/linux/obj-compiletest% make ARCH=mips 64r6el_defconfig
/usr/bin/make -C source O=/home/wfg/linux/obj-compiletest ARCH=mips CROSS_COMPILE=/usr/local/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- -j32 ARCH=mips 64r6el_defconfig
