preboot-override.patch

preboot-override.patch
Provide a place where the loader can patch the binary, such that it executes a
command string from RAM. We use this for automated installs, where we can thus
use the same u-boot binary for all stages.

include/configs/neo1973.h: new option CFG_PREBOOT_OVERRIDE to allow setting of
  the preboot command in memory
cpu/arm920t/start.S: added variable "preboot_override" at known location
  (_start+0x40)
common/main.c (main_loop): if preboot_override is set, execute the command
  string found there
common/env_common.c (env_relocate):  if preboot_override is set, always use the
  default environment
