Uwe Hermann ff7df4f7ad Add cross compilation support and simplify the far to complex serial
code (This goes hand in hand, as some parts of serial were hardcoded
to one architecture until now)

* include/uart8250.h: add TTYSx defines that are used in
  multiple places. formerly part of arch/x86/serial.c.
  Drop init_uart8250 (unused)
* lib/uart8250.c: drop arch/x86/config.h usage
  Drop init_uart8250 (unused)
* arch/powerpc/Kconfig, arch/x86/Kconfig: add CONFIG_ARCH to
  contain the directory name under LinuxBIOSv3/arch/
* arch/x86/console.c: drop some dead code. Drop hardcoded config.h values.
  use generic uart8250.h header
* arch/x86/cachemain.c: Drop hardcoded config.h values. Still use hardcoded
  ROM size for now. (To be changed later)
* arch/x86/config.h: dropped, no longer needed
* arch/x86/serial.c: factor out generically used defines to uart8250.h
* Makefile: use mainboard architecture instead of target architecture to choose
  include path.
  Read .xcompile if available (configure replacement).
  Create build.h with compile time and version.
* util/xcompile/xcompile: new file. Search for supported cross compilers
  linkers, assemblers (and potentially supported compiler flags etc)
  This is a very slick configure replacement.
* util/dtc/Makefile: fix Makefile for cross compilation

LinuxBIOS README
-------------------------------------------------------------------------------

LinuxBIOS is a Free Software project aimed at replacing the proprietary
BIOS you can find in most of today's computers.

It performs just a little bit of hardware initialization and then executes
one of many possible payloads, e.g. a Linux kernel.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by LinuxBIOS. Examples include:

 * A Linux kernel
 * FILO (a simple bootloader with filesystem support)
 * GRUB2 (a free bootloader; support is in development)
 * OpenBIOS (a free IEEE1275-1994 Open Firmware implementation)
 * Open Firmware (a free IEEE1275-1994 Open Firmware implementation)
 * SmartFirmware (a free IEEE1275-1994 Open Firmware implementation)
 * GNUFI (a free, UEFI-compatible firmware)
 * Etherboot (for network booting and booting from raw IDE or FILO)
 * ADLO (for booting Windows 2000 or OpenBSD)
 * Plan 9 (a distributed operating system)
 * memtest86 (for testing your RAM)


Supported Hardware
------------------

LinuxBIOS supports a wide range of chipsets, devices, and mainboards.

For details please consult:

Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the LinuxBIOS website:
