     2.8 +----------------------*
     2.9 +
    2.10 +An architecture is defined by:
    2.11 +
    2.12 + - a human-readable name, in lower case letters, with numbers as appropriate.
    2.13 +   The underscore is allowed. Eg.: arm, x86_64
    2.14 + - a boolean kconfig option named after the architecture (in capital letters
    2.15 +   if possible) prefixed with "ARCH_". Eg.: ARCH_ARM, ARCH_x86_64
    2.16 + - a directory in "arch/" named after the architecture, with the same letters
    2.17 +   as above. Eg.: arch/arm, arch/x86_64
    2.18 +   This directory contains:
    2.19 +   - a configuration file in kconfig syntax, named "config.in", which may be
    2.20 +     empty. Eg.: arch/arm/config.in
    2.21 +   - a function script in bash-3.0 syntax, named "functions", which shall
    2.22 +     follow the API defined below. Eg.: arch/arm/functions
    2.23 +
    2.24 +The "functions" file API:
    2.25 + > the function "CT_DoBuildTargetTuple"
    2.26 +   + parameters: none
    2.27 +   + environment:
    2.28 +      - all variables from the ".config" file,
    2.29 +      - the two variables "target_endian_eb" and "target_endian_el" which are
    2.30 +        the endiannes suffixes
    2.31 +   + return value: 0 upon success, !0 upon failure
    2.32 +   + provides:
    2.33 +     - the target tuple stored in the variable CT_TARGET_ARCH
    2.34 +
    2.35 + > the environment variable CT_ARCH_ENDIAN_OPT
    2.36 +   + contains:
    2.37 +     - the value of the CFLAGS values for selecting the endiannes (eg.: -ml
    2.38 +       for a Super-H little endian, -mbig-endian for an ARM big endian).
    2.39 +     - empty if the architecture can not set the endianness (eg x86 and
    2.40 +       x86_64).
