* 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 Blöm, 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.
