This patch adds rv32_defconfig for 32bit systems. The only
difference between rv32_defconfig and defconfig is that
rv32_defconfig has  CONFIG_ARCH_RV32I=y.

Thanks.  I think it makes sense to have this in 5.1 so I'm going to take it 
into the next RC.

Thanks, Palmer.

Can you consider "[PATCH v3] RISC-V: Fix Maximum Physical Memory 2GiB
option for 64bit systems" for 5.1?

Refer, https://patchwork.kernel.org/patch/10886895/

The above patch is also required for 64bit system with more than 128GiB memory
(i.e. server-class system).

We can remove "Maximum Physical Memory 2GiB" option as separate patch.

Regards,
Anup

Ya, that should go in.  It's on the branch, thanks for the reminder!
