ff6b092121 imx6: bootscript: use partition UUID for rootfs if possible
Specifying root filesystem by device is non-deterministic for several
reasons:
 - USB device unmeration order is not garunteeed for USB storage devs
 - MMC devs ordering is determined by the instance of the MMC host
   controller including non-storage SDIO devices which can throw off
   numbering depending on kernel versions.

It is recommended to use partition UUID

9ba09653ad treewide: remove maintainer variable from targets
There is no such role as target maintainer anymore, one should always
send corresponding changes for the review and anyone from the commiters
is allowed to merge them or eventually use the hand break and NACK them.

Lets make it clear, that it is solely a community doing the maintenance
tasks.

3666c67a54 imx6: add support for GW5907/GW5910/GW5912/GW5913
This patch adds support for GW5907/GW5910/GW5912/GW5913 IMX6 based boards
from the Gateworks Ventana Family[A]:
- backport upstream dt patches from 5.6 to 4.19 and 5.4
- add dtb's to ventana images
- add board-name and network config

A. https://www.gateworks.com/products/imx6-single-board-computer-gateworks-ventana-family

Flashing instructions for Ventana boards:

Using pre-flashed bootloader:
- Use appropriate ubi image depending on board NAND to flash via bootloader:
	openwrt-imx6-ventana-squashfs-nand.ubi - 2KiB page size
	openwrt-imx6-ventana-large-squashfs-nand.ubi - 4KiB page size
	http://trac.gateworks.com/wiki/linux/ubi

Using Gateworks JTAG dongle:
- Use Gateworks mkimage_jtag script to create a JTAG image comprised of
	pre-built bootloader and ubi image:

9c63141025 imx6: fix legacy IRQ support (4.19)
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.

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.

b9f926e151 imx6: rename Generic profile to Default, fixes u-boot image build issue
u-boot.mk checks for the Default profile to build images for all targets.
This brings the target default profile in sync with other targets

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.

67a3cdcbb0 kernel: enable THIN_ARCHIVES by default
THIN_ARCHIVES option is enabled by default in the kernel configuration
and no one target config disables it. So enable it by default and remove
this symbol from target specific configs to keep them light.
