Rebuilding RedBoot
These shell variables provide the platform-specific information needed for building RedBoot according to the
procedure described in
export TARGET=atlas_mips32_4kc
export TARGET=atlas_mips64_5kc
export ARCH_DIR=mips
export PLATFORM_DIR=atlas
Use one of the TARGET settings only.
The names of configuration files are listed above with the description of the associated modes.
