* Add support for 16 MB flash configuration of TRAB board 

* Patch by Erwin Rol, 27 Feb 2003:
  Add support for RTEMS

* Add image information to README

* Fix dual PCMCIA slot support (when running with just one
  slot populated)

* Add VFD type detection to trab board

* extend drivers/cs8900.c driver to synchronize  ethaddr  environment
  variable with value in the EEPROM

* Start adding MIPS support files

More About U-Boot Image Types:
------------------------------
U-Boot supports the following image types:
"Standalone Programs" are directly runnable in the environment
provided by U-Boot; it is expected that (if they behave
well) you can continue to work in U-Boot after return from
the Standalone Program.
"OS Kernel Images" are usually images of some Embedded OS which
will take over control completely. Usually these programs
will install their own set of exception handlers, device
drivers, set up the MMU, etc. - this means, that you cannot
expect to re-enter U-Boot except by resetting the CPU.
"RAMDisk Images" are more or less just data blocks, and their
parameters (address, size) are passed to an OS kernel that is
being started.
"Multi-File Images" contain several images, typically an OS
(Linux) kernel image and one or more data images like
RAMDisks. This construct is useful for instance when you want
to boot over the network using BOOTP etc., where the boot
server provides just a single image file, but you want to get
for instance an OS kernel and a RAMDisk image.
"Multi-File Images" start with a list of image sizes, each
image size (in bytes) specified by an "uint32_t" in network
byte order. This list is terminated by an "(uint32_t)0".
Immediately after the terminating 0 follow the images, one by
one, all aligned on "uint32_t" boundaries (size rounded up to
a multiple of 4 bytes).
"Firmware Images" are binary images containing firmware (like
U-Boot or FPGA images) which usually will be programmed to
flash memory.
"Script files" are command sequences that will be executed by
U-Boot's command interpreter; this feature is especially
useful when you configure U-Boot to use a real shell (hush)
as command interpreter.
