Hm... U-Boot 1.3.1 is more than 2 years old; Linux 2.6.19 is more than
3 years old. That's stone age for software.

Why are you working on such ancient software?  Do yourself (and us) a
favour  and upgrade - use recent code instead.  You will not get much
help for such old stuff...

Niklaus Wirth has lamented that, whereas Europeans pronounce his name
correctly  (Ni-klows  Virt),  Americans  invariably  mangle  it  into
(Nick-les  Worth).  Which  is to say that Europeans call him by name,
but Americans call him by value.
