* 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.
