The PCIe DWC host controller is now using MSI
(Message-signaled-interrupts) by default.
While ath9k itself does support MSI here, a lot of wlan adapters do not.
Avoid non-functioning cards by simply continue to disable MSI for now.
This can be done by appending "pci=nomsi" to the boot cmdline.
Also an extra fix needs to be backported which avoids MSI initialization
which prevented legacy IRQ's init from taking over.

This is probably theoretical problem as the Ventana is defined first in
the image Makefile, but once the position of the definition would change
in the future (alphabetical sorting?) it would get bootscript from the
previous board which would have BOOT_SCRIPT set.

Following errors were seen in the past on imx6 when using serial:
[ 22.617622] imx-uart 2020000.serial: DMA transaction error.
[ 22.623228] imx-uart 2020000.serial: DMA transaction error.
[ 22.628826] imx-uart 2020000.serial: DMA transaction error.
[ 22.648951] imx-uart 2020000.serial: DMA transaction error.
[ 22.654558] imx-uart 2020000.serial: DMA transaction error.
[ 22.660156] imx-uart 2020000.serial: DMA transaction error.
Which is the reason why DMA for the serial ports
got disabled in commits:
efb362cd93 ("imx6: disable dma on uart")
3b4241071d ("imx6: disable UART dma")
As indicated on mailinglist discussion, the cause seems to be
the usage of very old SDMA firmware which is present in the soc:
[ 0.624302] imx-sdma 20ec000.sdma: Direct firmware load for imx/sdma/sdma-imx6q.bin failed with error -2
[ 0.624318] imx-sdma 20ec000.sdma: Falling back to user helper
[ 64.531607] imx-sdma 20ec000.sdma: external firmware not found, using ROM firmware
This patch adds the new firmware binary. (2196 bytes)
It is required to embed the binary into the kernel image, as it
gets loaded very early in the boot process where the rootfs is not
available yet:
[ 0.622966] imx-sdma 20ec000.sdma: loaded firmware 3.3
Extended testing shows that the DMA errors are not seen anymore
when using this newer firmware version.

Built-in u-boot requires SPL (secondary program loader) to be present on the SD-card regardless of the image type which will be loaded.
SPL is generated by the u-boot-mx6cuboxi package which is preselected by the target device and can be found in bin/u-boot-mx6cuboxi directory.
Flashing the SPL:
dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=4
dd if=bin/targets/imx6/generic/u-boot-mx6cuboxi/SPL of=/dev/mmcblk0 bs=1K seek=1
Preparing the firmware on the SD-card:
(echo o; echo n; echo p; echo 1; echo ''; echo ''; echo w) | fdisk /dev/mmcblk0
mkfs.ext4 /dev/mmcblk0p1
mount /dev/mmcblk0p1 /mnt
tar -xzf bin/targets/imx6/generic/openwrt-imx6-device-cubox-i-rootfs.tar.gz -C /mnt/
mkdir -p /mnt/boot
cp bin/targets/imx6/generic/{*-uImage,*.dtb,*.scr} /mnt/boot/
Generated u-boot.img needs to be placed on the first partition:
cp bin/targets/imx6/generic/u-boot-mx6cuboxi/u-boot.img /mnt/
To boot from the SD card:
Boot script which sets mmc/dtb parameters and boots the board is automatically sourced.
If this does not work for any reason:
mmc dev 0; load mmc 0:1 $scriptaddr boot/boot.scr; source $scriptaddr
Currently imx6dl-cubox-i.dtb (Dual Lite) and imx6q-cubox-i.dtb (Quad) device trees are available.
Tested on i4Pro, MMC, USB (+ HiD), HDMI and ethernet ports are working.
Wireless and bluetooth are broken ATM. According to SolidRun forums, BCM4329/BCM4330 firmware is used which works fine on older kernels.

When this target got updated to 4.14, this patch got removed to

As the uart bus is very low bandwidth .. performance impact is negligible.

On Ventana boards the Gateworks System Controller is the only device on I2C1
(/dev/i2c-0) and it can NAK transfers if it is busy in an ADC loop. Because
this is a multi-function device with several slave addresses it is best to
