Hey Jesse,

There's a patch on the list (I think it came in after you sent v1) that
pointed out that the rv32_defconfig in the tree is not actually used if
you do `make ARCH=riscv rv32_defconfig`, but instead a make target is
used. How would you feel about replacing this final patch with the
below? That way rv32_nommu_virt_defconfig would always be kept in sync
with the rv64 version.

Cheers,
Conor.
