* Fix data abort exception handling for arm920t CPU

Browse Source 
* Fix alignment problems with flash driver for TRAB board

* Patch by Donald White, 21 May 2003:
  fix calculation of base address in pci_hose_config_device()

* Fix bug in command line parsing: "cmd1;cmd2" is supposed to always
  execute "cmd2", even if "cmd1" fails. Note that this is different
  to "run var1 var2" where the contents of "var2" will NOT be
  executed when a command in "var1" fails.
