All understood. And I asked if it was possible to integrate  it  like
NAND  boot  support  for  other  boards  is directly supported within

You think it's a lot of effort?

What a pitty...

I'm not sure that htis is  indeed  the  case.  I  just  said  that  I
consider the use of FP code in U-Boot a bug.

Why should we remove it when no FP is used?

I think this is primarily a toolchain issue, and the tools should  be
fixed.  But  of  course  there may be buggy code in the ARM port that
triggers the use of FP instructions - then this should be located and
cleaned up, too.
