Subject: * Patch by Gridish Shlomi, 30 Aug 2004:   - Add support to revA
 version of PQ27 and PQ27E.   - Reverted MPC8260ADS baudrate back to original
 115200

* Patch by Hojin, 17 Sep 2004:
  Fix typo in cfi_flash.c

* Patch by Mark Jonas, 09 September 2004:
  mtest's data line test (with CFG_ALT_MEMTEST set) returned a wrong
  error message

* Patch by Mark Jonas, 31 August 2004:
  Added option CFG_XLB_PIPELINING to enable XLB pipelining. This
  improves FTP performance for MPC5200 systems. Enabled for IceCube
  by default.
