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.
During an automatic update via USB stick, U-Boot searches for
images with the name "firmware.img" and "kernel.img". This names
are now changed to "firmw_01.img" and "kernl_01.img". This is done,
to prevent updates of new boards (with the new macronics "c" step
flashes) with old, incompatible firmware or kernel versions.
Patch by Martin Krause, 21 Jun 2006
- increase CFG_FLASH_ERASE_TOUT from 2 to 15 seconds
- use CFG_FLASH_WRITE_TOUT for programming instead of CFG_FLASH_ERASE_TOUT
- remove "Unlock Bypass" mode, because macronix flashes do not support
this mode officially
- fix flash reset command from 0x00FF to 0x00F0. 0x00FF is only specified
for Intel compatible flashes, not for AMD compatible.

Patch by Martin Krause, 08 Nov 2005
In tsc2000_read_channel() the delay after setting the multiplexer
to a temperature channel is increased from 1,5 ms to 10 ms. This
is to allow the multiplexer inputs to stabilize after huge steps
of the input signal level.
The environment variable "ver" is now set before
do_auto_update() is called, so that "ver" can be used
in USB update scripts.

ARM memory layout fixes: the abort-stack is now set up in the
correct RAM area, and the BSS is zeroed out as it should be.
Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
of the linker scripts are replaced by '__bss_start' and '_end',
resp., which is a further step to eliminate unnecessary differences
between the implementation of the CPU architectures.

Move most of the timer interrupt related PPC code to ppc_lib/interrupts.c

- /board/trab/trab_fkt.c: add new commands: gain, eeprom and power;
modify commands: touch and buzzer
* Disable CONFIG_SUPPORT_VFAT when used with CONFIG_AUTO_UPDATE

Use direct function calls for auto_update instead of hush commands
* Make fatload set filesize environment variable
fix potential buffer overlow problem

board; fix NAND code

configuration word supplied by FPGA on some MPC8260ADS boards
* Patch by Pantelis Antoniou, 10 Jun 2003:
Unify status LED interface
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)
* Fix alignment problems with flash driver for TRAB board
* Patch by Donald White, 21 May 2003:
fix calculation of base address in pci_hose_config_device()
* Fix bug in command line parsing: "cmd1;cmd2" is supposed to always
execute "cmd2", even if "cmd1" fails. Note that this is different
to "run var1 var2" where the contents of "var2" will NOT be
executed when a command in "var1" fails.
Update for R360MPI board
* Add new meaning to "autostart" environment variable:
If set to "no", a standalone image passed to the
"bootm" command will be copied to the load address
(and eventually uncompressed), but NOT be started.
This can be used to load and uncompress arbitrary
data.
* Set max brightness for MN11236 displays on TRAB board
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
boards, version 153 for Rev. 200 boards).

Fix relocation problem of statically initialized string pointers
in common/cmd_pci.c
* Patch by Kai-Uwe Blöm, 12 Mar 2003:

writing beyond the block boundaries.
- the length calculation for files was wrong, sometimes resulting
in short file reads.
- data copying now optionally takes fragment version numbers into
account, to avoid copying from older data.
See doc/README.JFFS2 for details.
