Steven,
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?
And you not only top-post, you also full-quote.
You are ignoring Netiquette more or less completely, are you aware of this?
I think you should read http://www.netmeister.org/news/learn2quote.html
really carefully.

1.2.0 is come frome eldk-4.1 iso file. Downloading independent u-boot seems require `git' tool which I get problem with because my office network gets many limits. Is there a http way to download u-boot?
If you bothered to read the documentation or tyhe U-Boot web pages you should have seen the links to the FTP site, and you should have read about the snapshot feature of git.
Please see http://www.denx.de/wiki/UBoot/SourceCode

The other platforms currently set a hard limit that should still be valid - I just changed the ones that were reading memsize directly out of the bd.

Sure, I just split it up in case there was some reason we shouldn't do it for one of them.

using flattened device tree (FDT)

Hi
It took me a evening to put everything together. Therefore I send this mail hoping it may help somebody else. Hopefully some of the content will find its way into the DULG/FAQ, may as point 14.3.30. "Booting using flattened device tree (FDT)"
First one needs a recent U-boot with FDT support compiled into, e.g 1.3.2-rc3-g772003e4-dirty (Apr 11 2008 - 15:56:0 for the sequoia board.
Secone one needs a recent Linux kernel made using "ARCH=powerpc", e.g. from 2.6.25-00002-ga9bf9f0 from git://www.denx.de/git/linux-2.6-denx.git.
Third one needs a recent dtc (Device Tree Compiler). The following commands
$ git clone http://www.jdl.com/software/dtc.git
$ cd dtc && make && sudo cp dtc /usr/local/bin
should do the job.
Now you are ready to compile the device tree blob. I used the commands given in
http://www.denx.de/wiki/view/DULG/LinuxFDTBlob
dtc -b 0 -V 17 -R 4 -S 0x3000 -I dts -O dtb -f arch/powerpc/boot/dts/sequoia.dts \

/tftpboot/sequoia/sequoia.dtb
Now power up your sequoia board and execute the following commands to start a
Linux kernel on a NFS root device. The following commands did the job for me:

Thats it. Now you should boot into your shiny new Linux kernel. Attached is a gzipped output of my startup (for the curious).
Once my kernel started I used the following commands to update my u-boot environment:
