sh: Remove old early serial console code V2
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.

- help
- Say Y here to redirect kernel printk messages to the serial port
- used by the SH-IPL bootloader, starting very early in the boot
- process and ending when the kernel's serial console is initialised.
- This option is only useful porting the kernel to a new machine,
- when the kernel may crash or hang before the serial console is
- initialised. If unsure, say N.
- On devices that are running SH-IPL and want to keep the port
- initialization consistent while not using the BIOS callbacks,
- select both the EARLY_SCIF_CONSOLE and SH_STANDARD_BIOS, using
- the kernel command line option to toggle back and forth.
