This patch adds support for serial output functions. It may be useful for debugging purposes since you can separate ordinary outputs from debugging dumps. Just add "serial.h", and use either serial_print or serial_puts as you would use printf and puts respectivelly. For QEMU, you only need to specify the option -serial stdio. If you use another VM, find how you can redirect the serial port to stdio. Signed-off-by: Raphael S.Carvalho <raphael.scarv at gmail.com> --- core/include/serial.h |...
