Uwe Hermann 3335adb771 This is a full rewrite of all the CS5530/CS5530A code. The previous code was 
mostly undocumented, had a broken coding style, contained lots of dead
code and had several other problems, e.g. it enabled write access to the
ROM (why?), it unconditionally enabled primary/secondary IDE (which should
have a config option) and that even _twice_ (which is um... wrong).

The new code

 - has 'ide0_enable' and 'ide1_enable' config options (which actually
   work) to enable/disable the primary/secondary IDE interface in
   Config.lb.

 - Does _not_ enable write access to the ROM (or is there some good
   reason to do that? If so, it should at least have a config option).

 - Contains a bit more documentation.

 - Uses readable (and documented) #defines instead of hardcoded magic values.

 - aaand... it actually compiles ;-) Yep, that's right. The previous code
   wouldn't even build, as it hadn't been fully ported from v1 (still used
   v1 functions which are simply not available in v2).

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.

guidelines and more can be found on the LinuxBIOS website:
