The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.
MAKEALL didn't report any errors related to this that I could see.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

adding support for Xilinx ML401
Change the xilinx device drivers and board code to include config.h
instead of xparameters.h directly. config.h always includes the
correct xparameters file. This change reduces the posibility of
including the wrong file when adding a new xilinx board port

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.
- Added I2C support for ML300.
- Added support for ML300 to read out its environment information
stored on the EEPROM.
- Added support to use board specific parameters as part of
U-Boot's environment information.
- Updated MLD files to support configuration for new features
above.
* Patches by Travis Sawyer, 5 Aug 2004:
- Remove incorrect bridge settings for eth group 6
- Add call to setup bridge in ppc_440x_eth_initialize
- Fix ppc_440x_eth_init to reset the phy only if its the
first time through, otherwise, just check the phy for the
autonegotiated speed/duplex. This allows the use of netconsole
- only print the speed/duplex the first time the phy is reset.
Add support for the Xilinx ML300 platform
* Patch by Stephan Linz, 17 Feb 2004:
Fix watchdog support for NIOS
* Patch by Josh Fryman, 16 Feb 2004:
Fix byte-swapping for cfi_flash.c for different bus widths
* Patch by Jon Diekema, 14 Jeb 2004:
Remove duplicate "FPGA Support" notes from the README file
- Allow to call sysmon function interactively
- PIC on LWMON board needs delay after power-on
- Add missing RSR definitions for MPC8xx
- Improve log buffer handling: guarantee clean reset after power-on
- Add support for EXBITGEN board
- Add support for SL8245 board
- 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)
