CAS-Latency=2, Write Recovery Time tWR=2
The max. supported bus frequency is 66 MHz. Therefore, changed
threshold to switch from 1:1 mode to 2:1 from 80 MHz to 66 MHz.

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
- Added LBA48 support (CONFIG_LBA48 & CFG_64BIT_LBA)
- Added support for 64bit printing in vsprintf (CFG_64BIT_VSPRINTF)
- Added support for 64bit strtoul (CFG_64BIT_STRTOUL)

Fix rarpboot: add autoload by NFS
* Patch by Dan Eisenhut, 26 Feb 2004:
fix flash_write return value in saveenv
* Patch by Stephan Linz, 11 Dec 2003
expand config.mk to avoid trigraph warnings on NIOS
* Rename "BMS2003" board into "HMI10"
see doc/README.MPC866 for details;
implement workaround for "SIU4" and "SIU9" silicon bugs on MPC866;
calculate CPU clock frequency from PLL register values.
* Add support for 128 MB RAM on TQM8xxL/M modules
before we can access it; add delay in case we are faster (with no
CF card inserted)
* Cleanup of some init functions
* Make sure SCC Ethernet is always stopped by the time we boot Linux
to avoid Linux crashes by early packets coming in.
* Accelerate flash accesses on LWMON board by using buffered writes
version of the repository???]
* Patch by Reinhard Meyer, 09 Jan 2004:
- add RTC support for MPC5200 based boards (requires RTC_XTAL)
* Add support for IDE LED on BMS2003 board
(exclusive with status LED!)
* Add support for PS/2 keyboard (used with PS/2 multiplexor on
BMS2003 board)
* Patches by Reinhard Meyer, 4 Jan 2004 + 7 Jan 2004:
Add common files for "emk" boards
* Minor code cleanup (coding style)
* Patch by Reinhard Meyer, 30 Dec 2003:
- cpu/mpc5xxx/fec.c: added CONFIG_PHY_ADDR, added CONFIG_PHY_TYPE,
- added CONFIG_PHY_ADDR to include/configs/IceCube.h,
- turned debug print of PHY registers into a function (called in two places)
- added support for EMK MPC5200 based modules
* Fix MPC8xx PLPRCR_MFD_SHIFT typo
* Add support for TQM866M modules
* Fixes for TQM855M with 4 MB flash (Am29DL163 = _no_ mirror bit flash)
* Fix a few compiler warnings
* Fix problems in memory test on some boards (which was not
non-destructive as intended)
* Patch by Gary Jennejohn, 28 Oct 2003:
Change fs/fat/fat.c to put I/O buffers in BSS instead on the stack
to prevent stack overflow on ARM systems
- Added Motorola CPU 8540/8560 support (cpu/85xx)
- Added Motorola MPC8540ADS board support (board/mpc8540ads)
- Added Motorola MPC8560ADS board support (board/mpc8560ads)
* Minor code cleanup
allow selection of clock frequency as "make" target
* Implement memory autosizing code for IceCube boards
* Configure network port on INCA-IP for autonegotiation
* Fix overflow problem in network timeout code
* Patch by Richard Woodruff, 8 Aug 2003:
Allow crc32 to be used at address 0x000 (crc32_no_comp, too).
* Add support for TQM823M, TQM850M, TQM855M and TQM860M modules
* Add support for Am29LV160ML, Am29LV320ML, and Am29LV640ML
mirror bit flash on TQM8xxM modules
- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
* Patch by Murray Jensen, 24 Jun 2003:
- make sure to use only U-boot provided header files
- fix problems with ".rodata.str1.4" section as used by GCC-3.x

* Add support for TQM862L at 100/50 MHz
* Patch by Pantelis Antoniou, 02 Jun 2003:
major reconstruction of networking code;
add "ping" support (outgoing only!)
instead CFG_MONITOR_LEN is now only used to determine _at_compile_
_time_ (!) if the environment is embedded within the U-Boot image,
or in a separate flash sector.
* Cleanup CFG_DER #defines in config files (wd maintained only)
