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.
* Debug message can be turned on and off.
* Waiting for events now times out.
* Implemented RESET command.
* Added appropriate nand_bbt_descriptor and nand_oobinfo.
Remaining Problems:
* Read Status still behaves weird an returns invalid stuff sometimes.
* ECC Placement does not respect our scheme in nand_oobinfo.
done so far:
* created zylonite board dir (based on lubbock)
* extended some - but not all pxa sources and headers for Intel
Monahans support (CONFIG_CPU_MONAHANS)
* created Makefile zylonite target + MAKEALL entry
* added some debug nonsense, remove later, grep for mk@tbd
Status: compiles (eldk-4.0), and can be started with BDI, but runs forever
and doesn't halt at breakpoints. Hmmm...
Correct addessing errors in platform files.
Split off common core module data from Integrator header files to
include/armcoremodule.h.

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
* Patch by Anders Larsen, 17 Sep 2003:
Bring ARM memory layout in sync with the documentation:
stack and malloc-heap are now located _below_ the U-Boot code
- Added Motorola CPU 8540/8560 support (cpu/85xx)

* Patch by Anders Larsen, 22 Sep 2003:
enable timed autoboot on PXA
* Patch by David Müller, 22 Sep 2003:
- add $(CFLAGS) to "-print-libgcc-filename" so compiler driver
returns correct libgcc file path
- "latency" reduction of busy-loop waiting to improve "U-Boot" boot
time on s3c24x0 systems
* Patch by Jon Diekema, 19 Sep 2003:
- Add CFG_FAULT_ECHO_LINK_DOWN option to echo the inverted Ethernet
link state to the fault LED.
- In NetLoop, make the Fault LED reflect the link status. The link
status gets updated on entry, and on timeouts.
- fix spelling errors
- set GD_FLG_DEVINIT flag only after device function pointers
are valid
- Allow CFG_ALT_MEMTEST on systems where address zero isn't
writeable

- trigger watchdog while waiting in serial driver
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.
