if you got files on the SD then your SD is partitioned and has a single
FAT partition. I'm not sure where you put your squash fs... as an image
file on the SD card (i.e on the FAT partition of the SD card )

>Actually this sounds like you have no mmc driver in your kernel.
I'm using the defconfig where
in make linux-menuconfig is selected the following:
+Device Drivers
<*> MMC/SD/SDIO card support
+ + <*> MMC block device driver
+ + <*> MMC host test driver
+ + <*> Atmel SD/MMC Driver (Atmel Multimedia Card Interface support)
+ + [ * ] Atmel MCI DMA support (Exp.)
well but now, that you mention it, it's weired. When I do a bootable image with this settings but with initramfs and busybox as init system then I should be able to see which devices are detected, right? So If I do ls /dev/ mmcblk or sdb isn't even in the list, is that a normal behaviour?

No, it's not.
The platform bindings may be missing in your board file.
Which board are you building for? A standard board or a custom one? In
the latter case, you should check with your kernel developer where to
find the MMC device.
