If the SoC is fused with eMMC reset enabled, the detection GPIO is
still set as an output.

Linux seems to require memory to be aligned by 2MiB to properly
use it as lowmem.

U-Boot typically tears down the display controller before handing
control over to Linux. On LCD displays disabling pixel clock leads to a
fading out effect with vertical/horizontal lines. Make sure to disable
back light before booting Linux.

Modify configuration for Tezi unified recovery mode:
- Enable SDP in U-Boot
- Enable FDT relocation (in-place is causing issues with FIT images)
- Remove video output
- Currently only for recovery (no flash/eMMC support)

The pad SAI1_RX_DATA can be used as second chip select for dual-die
NAND. However, with an assembly option the pad is available as GPIO
on SODIMM 169. All current version of Colibri iMX7 modules have the
pad available as GPIO hence do not mux the pin so that it is available
as GPIO by default.
This follows a similar commit in Linux ("arm: dts: imx7: mux pad of
SODIMM 169 as GPIO")

This adds support for Colibri iMX7 Dual 1GB modules which come
with on-board eMMC storage (whereas the other Colibri iMX7
modules use raw NAND). A subselection (variant) for the
Colibri iMX7 target is used to maximize sharing.

In case USB serial downloader has been used to load U-Boot start the
serial download protocol (SDP) emulation. This allows to download
complete images such as Toradex Easy Installer over USB SDP as well.
This code uses the boot ROM provided boot information to reliably
detect USB serial downloader.

If the Cortex-M4 is running we carve out 1MiB of memory for
rpmsg communication and/or the firmware running from DDR.
On the Colibri iMX7D this area is in the middle of its 512MiB
of memory. Linux seems not to handle the sparse memory area
well and shows only the first 254MiB of memory as available.
Enabling highmem seems to work around this issue. However,
enabling highmem is not ideal since memory from the highmem
area is more restricted then lowmem.
Aligning the carved out memory to ARM Linux' PMD (page middle
directory) size of 2MiB seem to allow allocating all available
memory as lowmem. Hence increase the carveout region to 2MiB.

Using linux,usable-memory the board code carves out 1MiB of memory
for the Cortex-M4 core at the end of the 256MiB block. However,
in case a board has 256MiB of memory (Colibri iMX7S), that is the
area where U-Boot gets relocated to... Use board_get_usable_ram_top
to avoid using that area as relocation target.

i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for
the rpmsg communication. Both use cases need a fixed location of
memory reserved. For the rpmsg use case the reserved area needs
to be in sync with the kernel's hardcoded vring descriptor location.
Use the linux,usable-memory property to carve out 1MB of memory
in case the M4 core is running. Also make sure that the i.MX 7
specific rpmsg driver does not get loaded in case we do not carve
out memory.

The config block support currently uses the ft_board_setup function
to patch the device tree with config block information. However, this
does not allow to patch the device tree with board specific information.
Rename the common setup function to ft_common_board_setup and use the
call it from the board files directly.

This commit adds support for the Toradex Computer on Modules
Colibri iMX7S/iMX7D. The two modules/SoC's are very similar hence
can be easily supported by one board. The board code detects RAM
size at runtime which is one of the differences between the two
boards. The board also uses the UART's in DTE mode, hence making
use of the new DTE support via serial DM.
