LMA XXX Overlaps Previous Sections When Using PHDRS

[DeRosa, Anthony]

Hello,

I want to install the contents of an ELF file on a flash device, using
the LMA of the sections (or rather p_paddr of program header) in the ELF
as the addresses in flash.  The VMA and LMA will thus be different.  I
am using "PHDRS" in my linker script in order to specify where the
various sections should be installed on flash.  The problem I am seeing
is the following message:

$ i686-elf-gcc -o test.elf test.S -T link.ld -nostartfiles

/opt/cross-tools/binutils-2.17-gcc-4.1.1-newlib-1.14.0/lib/gcc/i686-elf/
4.1.1/../../../../i686-elf/bin/ld: test.elf: section .section_0 lma
0x1000 overlaps previous sections

/opt/cross-tools/binutils-2.17-gcc-4.1.1-newlib-1.14.0/lib/gcc/i686-elf/
4.1.1/../../../../i686-elf/bin/ld: test.elf: section .section_1 lma
0x1020 overlaps previous sections


Is this a warning, an error, or neither?  Why does it say "lma 0x1000"?
I thought the VMA was 0x1000, and the LMA is 0x4000.

Here is the example code and a contrived linker script.
