 * xtensa/config/core.h -- HAL definitions dependent on CORE configuration
 *
 *  This header file is sometimes referred to as the "compile-time HAL" or CHAL.
 *  It pulls definitions tailored for a specific Xtensa processor configuration.
 *
 *  Sources for binaries meant to be configuration-independent generally avoid
 *  including this file (they may use the configuration-specific HAL library).
 *  It is normal for the HAL library source itself to include this file.
