06d01dbe00 * Avoid flicker on the TRAB's VFD by synchronizing the enable with
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
  boards, version 153 for Rev. 200 boards).

* Patch by Vladimir Gurevich, 12 Mar 2003:
  Fix relocation problem of statically initialized string pointers
  in common/cmd_pci.c

* Patch by Kai-Uwe Blm, 12 Mar 2003:
  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.

The ELPT860 CPU board has the following features:
Processor: - MPC860T @ 50MHz
- PowerPC Core
- 65 MIPS
- Caches: D->4KB, I->4KB
- CPM: 4 SCCs, 2 SMCs
- Ethernet 10/100
- SPI, I2C, PCMCIA, Parallel
CPU board: - DRAM: 16 MB
- FLASH: 512 KB + (2 * 4 MB)
- NVRAM: 128 KB
- 1 Serial link
- 2 Ethernet 10 BaseT Channels
On power-up the processor jumps to the address of 0x02000100
Thus, U-Boot is configured to reside in flash starting at the address of
0x02001000. The environment space is located in NVRAM separately from
U-Boot, at the address of 0x03000000.
