There is little misconfiguration, qemu for sam7x have no support nor flash,
ecos for 7x have no support ram startup. I never try ecos for sam7,
but this is not big problem.

I fixed this issue (below path to repo and branch where is fix). 
So little instruction for anybody who want try qemu with
at91 support:

$git clone --branch at91sam_support_for_merge git:// qemu_at91sam
$cd qemu_at91sam
$./configure --target-list="arm-softmmu arm-linux-user armeb-linux-user"

build at91sam7xek kernel and tests,
create binary file from some executable, for example:
$arm-eabi-objcopy -O binary bin_sem0 bin_sem0.bin

create flash image:

$dd if=/dev/zero of=/tmp/flash.bin count=128 bs=1024
$dd if=./bin_sem0.bin of=/tmp/flash.bin conv=notrunc

and run it:
$./arm-softmmu/qemu-system-arm   -serial tcp::4445,server  -M at91pes
-pflash /tmp/flash.bin &

connect to serial port:
$telnet localhost 4445
and you will see:
PASS:<Binary Semaphore 0 OK>
