[coreboot-gerrit] Change in ...coreboot[master]: RFC: riscv: Add initial support for 32bit boards

[Philipp Hug (Code Review)]

Hello ron minnich, Jonathan Neuschäfer, build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/31253

to look at the new patch set (#2).

Change subject: RFC: riscv: Add initial support for 32bit boards
......................................................................

RFC: riscv: Add initial support for 32bit boards

* Adding separate targets for 32bit and 64bit qemu
* Using the riscv64 toolchain for 32bit builds requires setting -m elf32lriscv
* Should we choose between rv32/rv64 per stage? ARCH_BOOTBLOCK_RISCV_RV32? How can we do that without having a separate rv32 toolchain?

TEST=Boots to "Payload not loaded." on 32bit qemu
