[U-Boot] mpq101 board broken

[Wolfgang Denk]

Dear Alex,

the mpq101 board support is broken in recent versions of U-Boot:

Configuring for mpq101 board...
ppc_85xxDP-ld: u-boot: section .ppcenv lma 0xfffc0000 overlaps previous sections

Can you please have a look?

Best regards,

Wolfgang Denk

I ran into this, too, but it went away when I updated my compiler. It
looks like the beginning was set a little too close to the end?

I pulled the git and recompiled, yet I don't see any errors, everything is
just fine. My compiler version is:
Using built-in specs.

Seems you are on thin ice.  I used gcc-4.2.2 for building, which
eventually optimizes a bit less efficient.

Is not this compiler version a good 4 years old?

In my blob I still got 8k free, and I don't think there's too much use
for NFS support, which is enabled by default.

Yes, it is.  And it is rock-solid, at least copmpared to gcc-4.4.x and
later.

See for example  http://www.denx.de/wiki/U-Boot/GccBugsAndIssues  for
just the list of regressions we ran into in U-Boot context.

Also keep in mind that for example the Linux README still says: "Make
sure you have at least gcc 3.2 available."  To me this suggests that
compiler versions that old are supposed to be still supported...

I just point out that this board does not build in our build tests -
as the only PPC board, btw.

The error says something about previous section. May be it's not directly 
compiler related at all.

As I'm putting .ppcenv to be the first section, the only thing before it
is .interp, which is supposed to be empty.

Do you have a linker map file for me to look at?

Linker map sent off list.

That's their goal, remember, a goal that's really contrary to that of
the programmer or administrator. We just want to get our  jobs  done.
