[PATCH v2 0/2] ARM: imx6: add new MarsBoard support

[Ahmad Fatoum]

I've picked up v1 of the patch from here:
https://barebox.infradead.narkive.com/mn9ZpGu6/patch-2-3-marsboard-add-new-board

and worked in the review feedback from back then.

v1 -> v2:
 - rebased on current upstream/next
 - removed seperate defconfig and added board to imx_v7_defconfig (Lucas)
 - added boot mode documentation
 - removed redundant VPU/IPU AXI configurations from DCD-Table (Sascha)
 - removed setting console in linux bootargs (Sascha)
 - have board-specific environment use bbenv-y in Makefile (Sascha)
 - added barebox device tree that includes kernel device tree
 - used imx6_uart_setup_ll and imx_setup_pad for debug_ll UART
 - used compressed DTB
 - used imx6q_barebox_entry instead of hardcoding RAM size

+Boot Configuration
+==================
+
+DIP Switch S1 on the board can be used to set ``BOOT_MODE1`` and
+``BOOT_MODE0`` going to the i.MX6:
+
+Set ``SW1 = 01`` for serial boot::
+
+        SW1
+        v.---.
+        1|o--| O
+        2|--o| N

+
+Set ``SW1 = 10`` for internal (SPI-NOR Flash) boot::

+        v.---.
+        1|--o| O
+        2|o--| N

+        2|o--| N
+         `---'
+
+Flashing barebox
+----------------
+
+  1. Connect to the boards's Debug Mini-USB (115200 8N1)
+
+  2. Set ``SW1 = 01`` for serial boot mode (see above)
+
+  3. Turn board's power on;
+
+  4. Upload barebox image to the board via imx-usb-loader
+
+.. code-block:: none
+
+  host$ imx-usb-loader images/barebox-embest-imx6q-marsboard.img
+..
+
+  4. Flash barebox to SPI-NOR Flash via Android Fastboot
+
+.. code-block:: none
+
+  target$ fastboot flash bbu-spiflash images/barebox-embest-imx6q-marsboard.img
+
+..
+
+  5. Resore ``SW1 = 10`` for internal (SPI-NOR) boot (see above)

[PATCH v2 2/2] ARM: imx_v7_defconfig: enable Embdest MarS board

[Ahmad Fatoum]

From: Ahmad Fatoum <ahmad@a3f.at>

Have it compile as part of the defconfig, to improve coverage.

+1 for good docu. It's really nice to have the boot jumpers documented.

'target' -> 'host', because the fastboot command is also executed on the
host machine, like the 'imx-usb-loader' command.

Apart from that

Tested-by: Stefan Lengfeld <contact@stefanchrist.eu>

for both patches.

Kind regards,
Stefan

I've sent out a fixup.

Thanks for trying it out.

Sascha, could you squash in the Tested-By when applying the fixup? Thanks.
