Well, I have to admit it was quite an emotion to see this the first time!

  Top of RAM usable for U-Boot at: 08000000
  Reserving 227k for U-Boot at: 07fc7000
  Reserving 4224k for malloc() at: 07ba7000
  Reserving 84 Bytes for Board Info at: 07ba6fac
  Reserving 76 Bytes for Global Data at: 07ba6f60

So far so good, but...

  Stack Pointer at: 07ba6f48
  New Stack Pointer is: 07ba6f48
  ?~??o   (<- garbage characters then nothing)

I can't say I'm surprised. I expected some trouble in the relocation.
As others before me, the u-boot code is correctly copied in RAM,
the code run from "in_ram:", but hangs in "trap_init:".
