This change is in preparation for condtitionial compile support in the
build system. By spliting them all into seperate lines now, subsequent
patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

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)
- Hymod board database mods: add "who" field and new xilinx chip types
- provide new "init_cmd_timeout()" function so code external to
"common/main.c" can use the "reset_cmd_timeout()" function before
entering the main loop
- add DTT support for adm1021 (new file dtt/adm1021.c; config
slightly different. see include/configs/hymod.h for an example
(requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
CFG_DTT_ADM1021 defined)
- add new "eeprom_probe()" function which has similar args and
behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
config.mk to allow board configurations to override the GNU
linker script, selected via the LDSCRIPT, make variable, and to
give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
o correctly extends the timeout depending on the size of all
queued messages for both transmit and receive
o will not continue with receive if transmit times out
o ensures that the error callback is done for all queued tx
and rx messages
o correctly detects both tx and rx timeouts, only delivers one to
the callback, and does not overwrite an earlier error
o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
technically correct
- many Hymod board changes
