2 | * Generic 16550 kgdb support intended to be useful on a variety | ||
3 | * of platforms. To enable this support, it is necessary to set | ||
4 | * the CONFIG_GEN550 option. Any virtual mapping of the serial | ||
5 | * port(s) to be used can be accomplished by setting | ||
6 | * ppc_md.early_serial_map to a platform-specific mapping function. | ||
7 | * | ||
8 | * Adapted from ppc4xx_kgdb.c. | ||
