These shell variables provide the platform-specific information needed for building RedBoot according to the
procedure described in
export TARGET=assabet
export ARCH_DIR=arm
export PLATFORM_DIR=sa11x0/assabet
The names of configuration files are listed above with the description of the associated modes.
