Now I have some issues for a already allocated gpio for a serial uart:

 > 21e8000.serial: ttymxc1 at MMIO 0x21e8000 (irq = 292, base_baud = 
5000000) is a IMX
 > imx6q-pinctrl 20e0000.iomuxc: pin MX6Q_PAD_EIM_D24 already requested

(MX6Q_PAD_EIM_D24) from group uart3grp  on device 20e0000.iomuxc
 > imx-uart 21ec000.serial: Error applying setting, reverse things back

Actually I do not see anything using the pin MX6Q_PAD_EIM_D24 in my 
device-tree, so I suspect something elsewhere...

And strangely enough, I can boot the kernel and the device tree from the 
mmc2 with Barebox:

>      `-- 0x02c00000-0x1d9bfffff ( 7.4 GiB): /dev/mmc2.2

but the kernel itself is unable to found any card:

maybe something related to the CD pin...??? I will check.


Great job!
As soon this board will be up and running, I will try to send some 
patches to include the support for this board in the future releases of 
Barebox.
