-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
