Yasha Cherikovsky 37f4565b8b coreinfo: Rewrite bootlog_module
The old bootlog_module implementation was completely broken:
- It assumed that the console buffer is located at address 0x90000,
  and of size 64K. It is not correct nowadays.
- It displayed the buffer in a very hacky way, the code was riddled with
  TODOs and FIXMEs. Scrolling had sometimes unexpected behavior.

The new implementation:
- Uses the cbmem console as the source of data.
  It takes the console information from lib_sysinfo of libpayload, which is
  constructed from the coreboot tables (no more hardcoded adressess).
- Properly sanitizes the console buffer for display, which makes
  scolling and display much easier to implement.

README

This is a silly little program that demonstrates how cool libpayload is
and also serves a purpose.  It is fun and educational!

Requirements
------------

You should use the coreboot reference cross compiler. If you insist on using
your system compiler, some Linux distributions might require you to install
a package called gcc-multilib if you are on a 64bit system.

Build
-----

You need libpayload to build coreinfo. So, first, you need follow the README of 
libpayload to build it but install libpayload into its own directory by doing 
this:

 $ make DESTDIR=/path/to/libpayload/install install

Then you can build coreinfo now:

 $ cd coreinfo

 $ make menuconfig
 
 $ make
