  "message": "serial: convert early_uart to earlycon for 8250\n\nBeacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and\ninclude/asm-x86_64/serial.h.  the serial8250_ports need to be probed late in\nserial initializing stage.  the console_init\u003d\u003eserial8250_console_init\u003d\u003e\nregister_console\u003d\u003eserial8250_console_setup will return -ENDEV, and console\nttyS0 can not be enabled at that time.  need to wait till uart_add_one_port in\ndrivers/serial/serial_core.c to call register_console to get console ttyS0.\nthat is too late.\n\nMake early_uart to use early_param, so uart console can be used earlier.  Make\nit to be bootconsole with CON_BOOT flag, so can use console handover feature.\nand it will switch to corresponding normal serial console automatically.\n\nnew command line will be:\n\tconsole\u003duart8250,io,0x3f8,9600n8\n\tconsole\u003duart8250,mmio,0xff5e0000,115200n8\nor\n\tearlycon\u003duart8250,io,0x3f8,9600n8\n\tearlycon\u003duart8250,mmio,0xff5e0000,115200n8\n\nit will print in very early stage:\n\tEarly serial console at I/O port 0x3f8 (options \u00279600n8\u0027)\n\tconsole [uart0] enabled\nlater for console it will print:\n\tconsole handover: boot [uart0] -\u003e real [ttyS0]\n\nSigned-off-by: \u003cyinghai.lu@sun.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Gerd Hoffmann \u003ckraxel@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
