[PATCH 0/1] dprintf: add debug console support
This patch adds support for printing messages through a debug console. QEMU,
for example, supports this through the debugcon facility. The benefit is that
it's *much* faster than printing over a serial port.
To print to I/O port 0x402 (the default used by SeaBIOS and OVMF),
add "-DDEBUG_IO_PORT=0x402 -DCORE_DEBUG=1" to the build CFLAGS.
To enable a debug console in QEMU that listens to I/O port 0x402 and prints to
stdio, add "-debugcon stdio -global isa-debugcon.iobase=0x402" to the QEMU
command line.
