2320 * @co: registering console

2322 * @idx: index from console command line
2323 * @options: ptr to option string from console command line
2324 *
2325 * Only attempts to match console command lines of the form:
2326 * console=pl011,mmio|mmio32,<addr>[,<options>]
2327 * console=pl011,0x<addr>[,<options>]
2328 * This form is used to register an initial earlycon boot console and
2329 * replace it with the amba_console at pl011 driver init.
2330 *
2331 * Performs console setup for a match (as required by interface)
2332 * If no <options> are specified, then assume the h/w is already setup.
2333 *
2334 * Returns 0 if console matches; otherwise non-zero to use default matching
