Now when the sh-sci driver can do early serial output, get rid of the old duplicated code. This patch is V2 and removes support for "earlyprintk=serial" together with the following kconfig options: CONFIG_EARLY_SCIF_CONSOLE CONFIG_EARLY_SCIF_CONSOLE_PORT CONFIG_EARLY_PRINTK With this patch applied "earlyprintk=" support is always built-in the SuperH kernel. For this to work the serial driver must have early platform support and in the case of sh-sci the serial console needs to be enabled: CONFIG_SERIAL_SH_SCI_CONSOLE=y So after enabling the SuperH SCI console kconfig option you also need to point out port using the kernel command line: "earlyprintk=sh-sci.N[,baudrate][,keep]" Remember that clocks may be disabled by the boot loader so you may have to do some board specific static clock setup before earlyprintk will work on your platform.
