Dear Andy,

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no longer actively maintained.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.


Best regards,
