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.
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.
- 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
- enable 3.rd UART (ST-UART) on PXA(XScale) CPUs
- trigger watchdog while waiting in serial driver
- 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)
- rewrite of the S3C24X0 register definitions stuff
- "driver" for the built-in S3C24X0 RTC
* Patches by Yuli Barcohen, 12 Jun 2003:
- Add MII support and Ethernet PHY initialization for MPC8260ADS board
- Fix incorrect SIUMCR initialisation caused by wrong Hard Reset
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)
