* 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.
