Thanks John, the Kernel now boots well. However it gives a kernel panic while mounting the root file sysem over NFS:

Looking up port of RPC 100003/2 on 10.190.3.103
RPC: sendmsg returned error 101
portmap: RPC call returned error 101
Root-NFS: Unable to get nfsd port number from server, using default

I couldn't figure out why error 101 /* Network is unreachable */ is given. Below is my current U-boot settings and a snapshot of the booting:

Here is a uboot setup that works with a freescale kernel:
bootdelay=5
baudrate=115200
preboot=echo;echo Type "run flash_nfs" to mount root filesystem over NFS;echo
autoload=no
ethact=FEC ETHERNET
ramargs=setenv bootargs root=/dev/ram rw
jffs2args=setenv bootargs root=/dev/mtdblock0 rw rootfstype=jffs2
addip=setenv bootargs $(bootargs)
ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):$(netdev):off
panic=1
flash_nfs=run nfsargs addip;bootm $(kernel_addr)
flash_self=run ramargs addip;bootm $(kernel_addr) $(ramdisk_addr)
flash_jffs2=run jffs2args;bootm $(kernel_addr)
net_nfs=tftp 200000 $(bootfile);run nfsargs addip;bootm
netdev=eth0
ethaddr=00:04:9f:22:33:44
bootfile=/tftpboot/uImage
kernel_addr=ffd00000
rootpath=/tftpboot/ltib
filesize=c9d700
fileaddr=1000000
gatewayip=172.27.255.254
netmask=255.255.0.0
ipaddr=172.27.152.99
serverip=172.27.152.5
bootcmd=run net_nfs
nfsargs=setenv bootargs console=ttyS0,115200 root=/dev/nfs rw
nfsroot=$(serverip):$(rootpath)
stdin=serial
stdout=serial
stderr=serial

Change ip info, bootfile, rootpath etc to fit you config.
If you want it to work with Sylvain's kernel then you need to change
ttyS0 to ttyPSC0.

Also add a printenv just before the bootm so you can verify that your
bootargs really are getting set correctly.
