Hi, in the linker script,

? why _edata is not here?

> _edata = .;
> . = ALIGN(4);

why _edata is there?
other sections between _sdata and _edata, are they needed to be modified?

Yes it could be there. I added this to the linker script because I
needed all sdram_regions for barebox to jump over all barebox memory
regions in memtest.
Another solution would be to add a another region for barebox_cmds or
something else, but I though that can be located in data, too.
