2014-08-10serial: Separate the serial hardware init and the serial console init.Gabe Black
You might want to use the serial hardware for something other than a console, or you might want to intercede in the serial stream to wrap it in another protocol. This is what you'd do to send output to GDB while using it to debug the payload.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

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.

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.
