The usual addresses are something like 0x40_0000 and up, whereas "RAM" sections are placed at addresses in the 0x2000_0000 range.

Is this for ELF or Mach-O?
It would be really helpful to see the listing of sections and segments from the binary.

ELF. The following listing has the sections present in the binary. Are segments something else?

To see segments, try readelf -l.
Also what address is printed with the error message?

I'm running into this also with an ELF file produced by Cypress PSoC Creator. It uses GCC but the final build step adds section .cyloadermeta, which seems to have the offending region.
I figured I would use objcopy to produce an ELF without it:
arm-none-eabi-objcopy: fixed.elf: warning: allocated section `.cyloadermeta' not in segment
Without that section, bloaty is happy with the ELF.
If it is helpful, I can build an ELF from one of the sample projects and share that.
