This is a pretty generic problem: old software and new tools (or vice
versa) don't mix.  Please update your U-Boot code and use at least the
vcersion thjat was included with ELDk 4.2, or - better - just jump to
a current release.

Well, of course the problem was fixed in the U-Boot tree, several
years ago.  One could invest the time and dig through the old change
logs, but that time would be better invested in updating your U-Boot
code.

There are most probably other, not so easily visable problems lurking
as well - the new compilers optimize much better, which for example
requires a number of changes when accessing device registers (using
I/O accessors with proper memory barriers instead of plain pointer
accesses).  The old code may simply not run, or not reliably.  But all
attempts trying to debug that are wasted time - more recent, fixed
code is available, so please use that.

Best regards,

Wolfgang Denk
