2014-05-17libpayload: Fix to properly disable serial consoleKyösti Mälkki
With coreboot builds with serial console disabled, there is no CB_TAG_SERIAL entry in coreboot tables. We ended up with lib_sysinfo.serial == NULL and serial_hardware_is_present == 1.

2013-05-15libpayload: Fix the logic for hardware-less serial consolesDave Frodin
This fixes the configuration where serial console output is being sent to non-existant hardware to be captured with I/O trapping. In this configuration where there isn't serial hardware present we still want to init the consoles. We just never want to read non-existant hardware.

2012-12-18libpayload: Check if serial console h/w is present before usingDave Frodin
The serial_io_havechar() and serial_io_getchar() functions will always see keystrokes available if the serial hardware isn't actually there. We will still output chars to non-existant hardware to allow virtual hardware to capture them.

This enables using the ACS_ curses macros with libpayload. The translation from ACS_ macros (or characters with attribute A_ALTCHARSET) is done using one acs map for the video console, one for serial console (xterm/vt100/vt220), and one fallback, from which an ASCII substitute is taken if the device specific map doesn't contain an entry (ie NUL).
