82b34c1f60 imx6: image: ventana: Add missing BOOT_SCRIPT variable
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.

74738c4b80 imx6: fix DMA transaction errors
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.

- Cores: 1
- Memory Size: 512MB
- GPU: GC880
- Wifi/Bluetooth: Optional
- USB 2.0 ports: 2
- Ethernet: 10/100/1000 Mbps

- SoC: i.MX6 Dual Lite
- Cores: 2
- Memory Size: 1GB
- GPU: GC2000
- Wifi/Bluetooth: Optional
- USB 2.0 ports: 2
- Ethernet: 10/100/1000 Mbps

CuBox i4Pro | i4x4:
- SoC: i.MX6 Quad
- Cores: 4
- Memory Size: 2/4 GB
- GPU: GC2000
- Wifi/Bluetooth: Build In
- USB 2.0 ports: 2
- Ethernet: 10/100/1000 Mbps

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.

efb362cd93 imx6: disable dma on uart
When this target got updated to 4.14, this patch got removed to
re-evaluate if it was still needed.

Extensive testing now shows this issue is still present.
Let's re-add the patch to fix it for now.

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

Boot log:

[   22.513051] imx-uart 2020000.serial: DMA transaction error.
[   22.522721] imx-uart 2020000.serial: DMA transaction error.

As a sidenote:
The patch mentiones an issue with RS485, but the bootlog
errors above were recorded with the uart ports in standard RS232 mode.

Compile/Run-tested on imx6/GW5200

Based on following upstream patch by Tim Harvey (Gateworks):

80a01b6582

TX complete DMA messages are getting missed.
This is also currently an issue in mainline.
For now we will disable DMA in serial/imx.c.
