Wolfgang Denk f0c0b3a9e6 Fix incorrect use of getenv() before relocation 
A large number of boards incorrectly used getenv() in their board init
code running before relocation.  In some cases this caused U-Boot to
hang when certain environment variables grew too long.
Fix the code to use getenv_r().
