Wolfgang Denk 14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Moving the environment to flash can be more reliable
