## help    Xtensa is a configurable and extensible processor architecture.
## help    Supporting a specific configuration typically requires minor
## help    modifications to a small set of configuration files in various
## help    development tools. This process is automated and only requires
## help    a configuration specific 'overlay' file.
## help
## help    For a custom configuration, select the XTENSA_CUSTOM option and
## help    provide the name of the processor configuration through the
## help    CT_ARCH_XTENSA_CUSTOM_NAME option.
## help
## help    The default option (ARCH_xtensa_fsf) uses a built-in configuration,
## help    which may or may not work for a particular Xtensa processor.
xtensa: add support for the configurable Xtensa architecture. The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core. Processor and SOC vendors can select from various processor options and even create customized instructions in addition to a base ISA to tailor the processor for a particular application. Because of the configurability, the build process requires one additional step for gcc, binutils, and gdb to update the default configuration. These configurations are packed into an 'overlay' tar image, and are simply untarred on top of the default configuration during the build.
