When a computer does not boot at all or the result is only a deep black screen, a very useful option can be to use a serial connector to get UART debug console and read it, looking for any useful hint. However, enabling UART debug console with a sufficient level of details slows down the boot process in most cases. This commit adds the capability to build debug images, using a special configuration file for coreboot with debug options. This is a simplistic way that works for now, but should be improved later on. These debug images will be generated in the bin-dbg/ directory instead of bin/ where regular images are located.

GNU Boot also builds some debug images that are shipped in separate debug archives (like gnuboot-0.1-rc3_x200_8mb_debug.tar.xz). The debug images have the following differences with the regular images: - The serial port is enabled, its speed is set to 115200, and the Coreboot debug level is set to 7. It's possible to bring it up to 8 without recompiling the image by modifying the cmos.default file inside the image. In addition POST codes are also printed on the serial port. - When the computer has a Coreboot build setting for that (all computers but QEMU have that), memory debugging is enabled. This can help diagnose RAM compatibility issues to potentially fix them in Coreboot.
