Just tested with the first 3 patches applied the following defconfig:

BR2_riscv=y
# BR2_USE_MMU is not set

It fails to build with:

/home/thomas/buildroot/buildroot/output/host/riscv64-buildroot-linux-uclibc/bin/elf2flt: Loading to RAM ('-r' option) 
is required

This is using the default Busybox configuration, i.e
package/busybox/busybox.config. I haven't tested if other noMMU
architectures exhibit the same issue.

The package/busybox/busybox-minimal.config causes the same issue.

I'm gonna try on ARM noMMU and see.

Best regards,

Thomas
