in NAND for now. This will be added in a short while.
Patch by Stefan Roese, 07 Sep 2006
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.
- Support for TQM8541/8555 boards added.
- Complete rework of TQM8540/8560 support.
- Common TQM85xx code now supports all current TQM85xx platforms
(TQM8540/8541/8555/8560).
- DDR SDRAM size detection added.
- CAS latency default values can be overwritten by setting "serial#"
to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
If problems are detected with this non default CAS latency,
the defualt values will be used instead.
- FLASH size detection added.
- Moved FCC ethernet driver initialization behind TSEC driver init
-> TSEC is first device.
Patch by Stefan Roese, 30 Nov 2005
The global data pointer, stored in r29 before relocation to RAM, was
not initialized to a correct value. This happened because the pointer
declaration was done locally in the scope of the board_init_f()
function. What follows is a cite from gcc.info, 5.37, "Variables in
Specified Registers":
...
The compiler's data flow analysis is capable of determining where
the specified registers contain live values, and where they are
available for other uses. Stores into local register variables
may be deleted when they appear to be dead according to dataflow
analysis. References to local register variables may be deleted
or moved or simplified.
...
Moving the global data declaration to global scope solved the
problem.
Second serial port on 440GX now defined as a system device.

- Convert the CPM2 based functionality to use new CONFIG_CPM2
option rather than a myriad of CONFIG_MPC8560-like variants.
Applies to MPC85xx and MPC8260 boards, includes stxgp3 and sbc8560.
Eliminates the CONFIG_MPC8560 option entirely. Distributes the
new CONFIG_CPM2 option to each 8260 board.
