LM75 bug fix for negative temperatures

current driver does not perform sign extension, so the result returned is

lwmon5: enable hardware watchdog
Some boards (e.g. lwmon5) may use rather small watchdog intervals, so
causing it to reboot the board if U-Boot does a long busy-wait with
udelay(). Thus, for these boards we have to restart WD more
frequently.
This patch splits the busy-wait udelay() into smaller, predefined,
intervals, so that the watchdog timer may be resetted with the
configurable (CONFIG_WD_PERIOD) interval.

ppc: Allow boards to specify effective amount of memory
For historical reasons we limited the stack to 256M because some boards

mapping more memory (for example 85xx is capable of doing up to 2G).

If any of the steps for generating autoconf.mk fail currently, they go

easylogo: clean up some more and add -r (rgb) support
Michael Hennerich added support for outputting an image in RGB format rather
than forcing YUYV all the time. This makes obvious sense if the display you

Rather than hack in support for options, I've converted it to use getopt and
cleaned up the argument parsing in the process.

Makefile: add target for $(LDSCRIPT)
If the $(LDSCRIPT) does not exist (normally it's board/$(BOARD)/u-boot.lds),
then change into the board directory and try and create it. This allows you
to generate the linker script on the fly based upon board defines (like the
Blackfin boards do).
There should be no regressions due to this change as the normal case is to
already have a u-boot.lds file. If that's the case, then there's nothing to
generate, and so make will always exit. The fix here is that if the linker
script does not exist, the implicit rules take over and attempt to guess how
to generate the file.
Do not use uninitialized cmd_reset; issue both AMD and Intel reset
commands instead
From a short test, it looks like AMD-style flash roms treat *any* unknown
command write as a reset, at least when in CFI Query mode, so issuing the
Intel reset command to AMD-style flashs seems safe (from the small sample I
have), plus the 3-cycle magic sequence should kick the state machine into
the right state even without a reset command. Since the AMD-style flashs
require the unlock sequence for real operation, I chose to try the AMD reset
command first, so that Intel flashs do no see an invalid command prior to
the CFI query.
I have tested the patch on AM29LV320-style flashs from Fujitsu and Macronix,
plus Intel StrataFlash.

The CPU POST test code (run from cpu_post_exec_31()) doesn't follow the

OneNAND Initial Program Loader (IPL) support
This patch enables the OneNAND boot within U-Boot.
Before this work, we used another OneNAND IPL called X-Loader based
on open source. With this work, we can build the oneboot.bin image
without other program.
The build sequence is simple.
First, it compiles the u-boot.bin
Second, it compiles OneNAND IPL
Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
The mechanism is similar with NAND boot except it boots from itself.
Another thing is that you can only use the OneNAND IPL only to work
other bootloader such as RedBoot and so on.
