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.

This patch adds a generic command for programming I2C bootstrap
eeproms on PPC4xx. An implementation for Canyonlands board is
included.
The command name is intentionally chosen not to be PPC4xx specific.
This way other CPU's/SoC's can implement a similar command under
the same name, perhaps with a different syntax.
Usage on Canyonlands:
=> chip_config
Available configurations (I2C address 0x52):
600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100
600-nand - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100
800-nor - NOR CPU: 800 PLB: 200 OPB: 100 EBC: 100
800-nand - NAND CPU: 800 PLB: 200 OPB: 100 EBC: 100
1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100
1000-nand - NAND CPU:1000 PLB: 200 OPB: 100 EBC: 100
1066-nor - NOR CPU:1066 PLB: 266 OPB: 88 EBC: 88 ***
1066-nand - NAND CPU:1066 PLB: 266 OPB: 88 EBC: 88
=> chip_config 600-nor
Using configuration:
600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100
done (dump via 'i2c md 52 0.1 10')
Reset the board for the changes to take effect
Other 4xx boards will be migrated to use this command soon
as well.

460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.
This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.
Tested with 512 byte page NAND device (32MByte) on Canyonlands.

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.
- 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)
