Thank you very very very very very much !!! Ahmed !! :-)
I've apply the patch file to my source.
So, i success booting "Hello world + L4/Fiasco" on Freescale i.MX6 Quad
SABRE SD board.
Again, thank you for great help Ahmed and Tim, Matthias. :-)
Other peoples might have help from my thread for booting on my board or
not, I'll share my document for booting on my board after elaborating
it. :-)
Thank you L4 hackers.

Sorry but the git tree is private.
It’s pretty clear from the men_layout-arm-imx.cpp you attached what needs to be
changed:
Uart_phys_base needs to be Uart1_phys_base …

I've looked closely at the patch file you gave me .
I've found that uart-imx.cpp and imx.cc could be applied by the patch file but
there is some difference between your 'mem_layout-arm-imx.cpp' and my
'mem_layout-arm-imx.cpp'.
So, I was able to not apply the patch file to my 'mem_layout-arm-imx.cpp'.
How do you think about that ?
Attached is my 'mem_layout-arm-imx.cpp'.
I'm using a svn repository of which URL is
"http://svn.tudos.org/repos/oc/tudos/trunk/repomgr | perl -
inithttp://svn.tudos.org/repos/oc/tudos fiasco l4re".
If you use other git repository, I want to tell me it's URL ,please .

Hello, l4 hacker.
I'm trying to boot "Hello world / L4/ Fiasco" on Freescale i.MX6 Quad SABRE SD
board(Cortex-A9, ARMv7).
I'm using 'u-boot' and 'uImage'.
So, i build uimage by "make uimage E=hello ~...".
And i've try to booting it on Freescale i.MX6q_sabre_sd board.
But i did not it because stoped at "Starting kernel ..." !!
Probably you selected the wrong UART, so the system is not printing something
on the serial line. Make sure you have the right UART driver for your platform
and make sure you have selected the right one. Usually there are more than one
UARTs and only one is connected to you serial line. You can also check Linux to
see which UART it uses.
MMC read: dev # 2, block # 2048, count 8192 ... 8192 blocks read: OK

uimage's file name is "bootstrap_hello.uimage".
"bootstrap_hello.uimage" has information such as
"bootstrap_hello.uimage: u-boot legacy uImage, L4 Image #2, Linux/ARM, OS

I have a question.
Can you tell me function name that means 'Entry Point: 0x11000000' ?
In the uimage format the entry point is defined as the address where uboot
should start, as the name implies, the execution of the image.
Matthias.
