-arch/x86/include/README.txt
-^^^^^^^^^^^^^^^^^^^^^^^^^^^

-This directory holds x86-specific header files.  The top-level header files in
-arch/x86/include simply include corresponding header files from lower lower-
-level chip-specific and architecture-specific directories.
-
-Architecture-Specific Directories
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Architecture-specific directories hold common header files for specific x86
-architectures.  Separating these header file makes it easy to manage such
-things as differences in sizeof(long) on 32- and 64-bit x86 architectures.
-
-i486
-  This directory holds definitions appropriate for any instantiation of the
-  32-bit i486 architecture.
-
-Chip-Specific directories
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The same x86 architecture may be realized in different chip implementations.
-For SoC chips, in particular, on-chip devices and differing interrupt
-structures may require special, chip-specific definitions in these chip-
-specific directories.
-
-qemu
-  This is the implementation of NuttX on the QEMU x86 simulation.
