With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

The TK885D board uses a TQM885D module from TQ, this port adds an
own configuration file and adds a last_stage_init() method to
configure the two PHYs, depending on the phy_auto_nego environment
variable.

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)
* Patch by Masami Komiya, 27 Feb 2004:
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???]

* 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)

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 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)
