Warm boot bug has returned on DFB1

Hi Anders,

Looks like the latest version of MAPROM has re-introduced an old bug where after a warm boot results in no TT-RAM being allocated. I'm not sure the ROM is being mapped into ST-RAM or not at that stage, I'm afraid.

Not urgent at all. Cold boot obvious work around & v2.2 still works.

Cheers,
