[yocto] should i have known about "use-kernel-config"?

condensed version: i want to define a new machine for the MIPS
SEAD3, which is 32-bit, little endian, and it seemed pretty
straightforward, using the routerstation pro as a starting point and
making the appropriate tweaks.
i chose to base off of linux-yocto-3.8, and chose the
standard/mti-malta32 branch, then wanted to make sure i had an
appropriate defconfig. turns out there *is* a
arch/mips/configs/sead3_defconfig file in that branch, with exactly
the two settings i cared most about right at the top:
CONFIG_MIPS_SEAD3=y
CONFIG_CPU_LITTLE_ENDIAN=y
so all i wanted was to say, "use *that* as the defconfig", but i saw
nothing in the kernel guide that explained how until i tripped over
this in one of the meta-arago defconfig files:
use-kernel-config=am335x_evm_defconfig
does that do what i *think* it does? because it's certainly not
mentioned anywhere in the yocto docs. and it's kind of handy.
