* 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.
