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.

Change all linker scripts to reference the changed driver name 4xx_uart.o.
Note: In most cased all these explicit referencing of these object files
in the linker scripts is not neccessary. Only for manually embedded
environment into the U-Boot image, which is not done is most cases.

This patch adds support for multiple I2C busses on the PPC4xx
platforms. Define CONFIG_I2C_MULTI_BUS in the board config file
to make use of this feature.
It also merges the 405 and 440 i2c header files into one common
file 4xx_i2c.h.
Also the 4xx i2c reset procedure is reworked since I experienced
some problems with the first access on the 440SPe Katmai board.

Each of the filesystem drivers duplicate the get_dev routine. This change
merges them into a single function in part.c

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.
- update board/emk tree; use common flash driver
- Corrected tested bits in machine check exception in cpu/mpc5xxx/traps.c
[adapted for other PPC CPUs -- wd]
- Added support for the M48T08 on the EVAL5200 board in rtc/mk48t59.c
* Patch by Jon Diekema, 13 Feb 2004:
Call show_boot_progress() whenever POST "FAILED" is printed.
* Patch by Nishant Kamat, 13 Feb 2004:
Add support for TI OMAP1610 H2 Board
Fixes for cpu/arm926ejs/interrupt.c
(based on Richard Woodruff's patch for arm925, 16 Oct 03)
Fix for a timer bug in OMAP1610 Innovator
Add support for CS0 (ROM)/CS3 (Flash) boot in OMAP1610 Innovator and H2
* Patches by Stephan Linz, 12 Feb 2004:
- add support for NIOS timer with variable period preload counter value
- prepare POST framework support for NIOS targets
* Patch by Denis Peter, 11 Feb 2004:
add POST support for the MIP405 board
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
- add support for Altera Nios-32 CPU
- add support for Nios Cyclone Development Kit (DK-1C20)
* Patch by Steven Scholz, 29 Sep 2003:
- A second parameter for bootm overwrites the load address for
"Standalone Application" images.
- bootm sets environment variable "filesize" to the resulting
(uncompressed) data length for "Standalone Application" images
when autostart is set to "no". Now you can do something like
if bootm $fpgadata $some_free_ram ; then
fpga load 0 $some_free_ram $filesize
fi
* Patch by Denis Peter, 25 Sept 2003:
add support for the MIP405 Rev. C board
add FAT support for IDE, SCSI and USB
* Patches by Gleb Natapov, 2 Sep 2003:
- cleanup of POST code for unsupported architectures
- MPC824x locks way0 of data cache for use as initial RAM;
this patch unlocks it after relocation to RAM and invalidates
the locked entries.

- eliminates use of global variables, plus dead code, cleanup.
applications: instead of using (PPC-specific) system calls we now
use a jump table; please see doc/README.standalone for details
* Patch by Dave Westwood, 24 Jul 2003:
added support for Unity OS (a proprietary OS)
- remove trailing white space, trailing empty lines, C++ comments, etc.
