   3 ======================================================================
   4
   5 * Patch by Stefan Roese, 20 Mar 2003:
   6   - CPCI4052 update (support for revision 3).
   7   - Set edge conditioning circuitry on PPC405GPr for compatibility
   8     to existing PPC405GP designs.
   9   - Clip udiv to 5 bits on PPC405 (serial.c).
  10
  11 * Avoid flicker on the TRAB's VFD by synchronizing the enable with
  12   the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
  13   boards, version 153 for Rev. 200 boards).
  14
  15 * Patch by Vladimir Gurevich, 12 Mar 2003:
  16   Fix relocation problem of statically initialized string pointers
  17   in common/cmd_pci.c
  18
  19 * Patch by Kai-Uwe Blöm, 12 Mar 2003:
  20   Cleanup & bug fixes for JFFS2 code:
  21   - the memory mangement was broken. It caused havoc on malloc by
  22     writing beyond the block boundaries.
  23   - the length calculation for files was wrong, sometimes resulting
  24     in short file reads.
  25   - data copying now optionally takes fragment version numbers into
  26     account, to avoid copying from older data.
  27   See doc/README.JFFS2 for details.
  28
  29 * Patch by Josef Wagner, 12 Mar 2003:

 174
 175 * Update baudrate in bd_info when it gets changed

 181   (figuration of the utility, using a config file)
 182
 183 * Add single quote support for (old) command line parser
 184
 185 * Switch LWMON board default config from FRAM to EEPROM;
 186   in POST, EEPROM shows up on 8 addresses

 197 * Improve log buffer code; use "loglevel" to decide which messages
 198   to log on the console, too (like in Linux); get rid of "logstart"
 199
 200 * Add command line tool to access the U-Boot's environment
 201   (board-specific for TRAB now, to be fixed later)

 269   processing the receive buffers slower than the network controller
 270   was filling them.
 271
