Hi Cedric MAUSSIRE,
P2020RDB-PCA Board gets supported since kernel 3.3 in mainline code.
Are you sure the board works on kernel 2.6.35?

Subject: Cannot boot an kernel version other than 2.6.35 on P2020RDB-PCA
I am currently working on the Freescale P2020RDB-PCA Board, which has been delivred with the linux-2.6.35 kernel. I succeed in re-generating my own uImage in 2.6.35 thanks to ELDK, but when I want to move on to a newer or older version of linux, the system does not respond any longer just after the boot whith the nfsboot command, the logs are :
## Booting kernel from Legacy Image at 01000000 ...
Image Name: Linux-2.6.39
Created: 2012-05-29 8:24:54 UTC
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 3514882 Bytes = 3.4 MiB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
## Flattened Device Tree blob at 00c00000
Booting using the fdt blob at 0xc00000
Uncompressing Kernel Image ... OK
Loading Device Tree to 00ffa000, end 00fffd4a ... OK
NB : nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=192.168.1.1:$rootpath ip=192.168.1.2:192.168.1.1:192.168.1.1:255.255.255.0:P2020RDB-PC:eth0:off console=ttyS0,115200
I have unsuccessfully tried to rebuild the device tree blob and use the default kernel configuration "mpc85xx_defconfig" that comes with the mainline code.
My systems seems to be linux-2.6.35 dependent, I do not known how it can be possible, because I can use the kernel.org source of the 2.6.35 whith no problems but when I use the 3.0, for example, with the same configuration but it does not work.
