[meta-freescale] imx53qsb + yocto + latest kernel.

[ssinfod ssinfod]

Hello,
I see the uImage file in my deploy folder. The details of this file are:
 Folder: /home/dev/fsl-community-bsp/build/tmp/deploy/images/imx53qsb
 File:  uImage--3.14+git0+c34636a557-r0-imx53qsb-20140702201837.bin

However, I think there is a problem with the
"core-image-base-imx53qsb.sdcard"

Normally, with the 'old' kernel, I write this .sdcard and I have 2
partitions. (kernel and rootfs).

Now, when I use the line PREFERRED_PROVIDER_virtual/kernel = "linux-fslc",
it seems that the .sdcard doesn't have the kernel in it. It seems it only
has the rootfs in it.

Is that normal ? Is this happening because I am using the latest kernel ?
(linux-fslc)
Do I have to write both partitions manually ?
If so, how can I write the uImage and rootfs manually with the dd command ?


I have a final general question about the imx53:
Why the Freescale imx53 does not support the latest kernel by default ?

Right now, it seems to be a bad idea to use the imx53 since it currently
does not even support the latest kernel. What would it be in 5 years ?
Would it be stuck with kernel 2.6.35 ? Why Freescale is freezing the
support of the imx53 to that specific kernel ?

For a new design, should I use the Freescale imx6 instead of the imx53 ?

Thanks for your time,
ssinfod.
