Bug Description

I have a function linked at 0x82_000 (main)
It is reported as such when using the following commands:

arm-none-eabi-objdump -S nvmctrl_basic_rww_VCS_RTL_TEST_RAWWB.elf > out.dis
arm-none-eabi-nm -S nvmctrl_basic_rww_VCS_RTL_TEST_RAWWB.elf

But when I use objcopy to generate the image loadable by a verilog simulator (readmemh function) then my main function is wrongly mapped at 0xE000

To see the issue you can execute the following:
arm-none-eabi-objcopy --only-section=".sbankh" -O verilog nvmctrl_basic_rww_VCS_RTL_TEST_RAWWB.elf out.hex

The code should be @82_000 but it is located at @C000+padded with 0 (+0x2000).

Same issue with:

arm-none-eabi-objcopy -V
GNU objcopy (GNU Tools for ARM Embedded Processors) 2.24.0.20150304

But I didn't regenerate the elf file with this version.
