Uwe Hermann f5a6fd253c Various 440BX and Tyan S1846 related minor changes and fixes (trivial):
- Only check the RAM from 0 - 640 KB and 768 KB - 1 MB now. That's
   available on all boards, regardless of what DIMMs you use.
   Tested on the Tyan S1846, works fine.

 - Properly set the PAM registers to allow the region from 768 KB - 1 MB
   to be used as normal RAM (required for the above).

 - Document all of this properly. Add/improve other documentation, too.

 - Simplify and document code in northbridge.c.

 - Cosmetics and coding style.

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.
