[U-Boot] TQM85xx boards failing on older gcc

[Andy Fleming]

Stefan,

One of my coworkers is seeing these errors with gcc-4.3.74 (eglibc-2.8.74-6):


Configuring for TQM8548_BE - Board: TQM85xx, Options:
MPC8548,TQM8548_BE=y,HOSTNAME=tqm8548,BOARDNAME="TQM8548_BE"

He says the same for TQM8541, TQM8548. I don't see it on my 4.5.55 gcc

I was able to reproduce this error by using ELDK 4.2 (gcc 4.2.2) at least for 
TQM8541 and TQM8548. ELDK 5.2 (gcc 4.6.1) does not have this problem. I assume 
that the image size has increased over the time.

Not sure if we really need to remove some config option to make it fit again 
for the older toolchains. Or if its enough to support these targets with newer 
toolchains.

Thanks,
Stefan

glibc version should be completely irrelevant when building U-Boot.

I confirm that these are known issues.  Currently we have no intention
to fix these, though.  The boards in question have reached EOL and are
no longer actively maintained.  The problem is - as Stefan correctly
diagnosed - caused by increased code size due to some extensions and
fixes in recent versions, which do not cuase problems with recent tool
chains, but which would require either removal of functionality or
changes to the memory map for older tool chains with not so decent
code optimizations.  We feel that any of these activities would be
wasted efforts, so we decided to ignore these issues.

In case the boards should break with recent tool chains, I will
probably board send removal patches.

Thanks

Best regards,

Wolfgang Denk

Yeah, I only mentioned it because it was part of the versioning string.

That's fine by me. My coworker has upgraded his gcc, so he no longer
sees the issue. I'll let you know if it stops building, in the future.
