History
Wolfgang Denk 25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value 
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

U-Boot for Hidden Dragon board
------------------------------

Hidden Dragon is a MPC824x-based board by Motorola. For the most
part it is similar to Sandpoint8245 board. So unless otherwise
mentioned, the codes in this directory are adapted from ../sandpoint
directory.

Apparently there are very few of this board out there. Even Motorola
website does not have any info on it.

RAM:
  start = 0x0000 0000
  size	= 0x0200 0000 (32 MB)

Flash:
  BANK ONE:
    start = 0xFFE0 0000
    size  = 0x0020 0000 (2 MB)
    flash chip = 29LV160TE (1x16 Mbits or 2x8 Mbits)
    flash sectors = 16K, 2x8K, 32K, 31x64K

  BANK TWO:
    NONE

The processor interrupt vectors reside on the first 256 bytes
starting from address 0xFFF00000. The "reset vector" (first
instruction executed after reset) is located on 0xFFF0 0100.

U-Boot is configured to reside in flash starting at the address of
0xFFF00000. The environment space is located in flash separately from
U-Boot, at the second sector of the first flash bank, starting from
0xFFE04000 until 0xFFE06000 (8KB).

Network:
  - RTL8139 chip on the base board	  (SUPPORTED)
  - RTL8129 chip on the processor board	  (NOT SUPPORTED)

Serial:
  - Two NS16550 compatible UART on the processor board	(SUPPORTED)
  - One NS16550 compatible UART on the base board	(UNTESTED)

Misc:
  VIA686A PCI SuperIO peripheral controller
  - 2 USB ports		    (UNTESTED)
  - 2 PS2 ports		    (UNTESTED)
  - Parallel port	    (UNTESTED)
  - IDE & floppy interface  (UNTESTED)

  S3 Savage4 video card	    (UNTESTED)

TODO:
-----
- Support for the VIA686A based peripherals
- The RTL8139 driver frequently gives rx error.
- Support for RTL8129 network controller. (Why is the support removed from
  rtl8139.c driver?)
