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.

Added removal of the fsl,ext-reset-output property in the wdog node for board
revisions that pre-date the addition of the external watchdog reset signal.
This property is a recent addition to mainline linux kernel in order to
specify that the IMX watchdog external reset should be used instead of the
internal chip-level reset.

The hwconfig env var allows user to control hardware specific configuration
of board specific features but not all Ventana boards have the same features.
We will use the magic default value of "_UNKNOWN_" to signify that the

3b1f681131 caused a regression that removes
board info dispaly for Gateworks Ventana boards because it made the invalid
assumption that CONFIG_DISPLAY_BOARDINFO_LATE was the same thing as
CONFIG_DISPLAY_BOARDINFO.
Ventana needs to call show_board_info in late init because we need to have
the i2c eeprom based model info. Re-define CONFIG_DISPLAY_BOARDINFO_LATE
to allow that to happen.

The IMX6 PCIe host controller does not have a proper reset and as such there
are several issues that can arise if PCI is enabled in the bootloader follwed
by Linux trying to re-configure LTSSM and/or toggling PERST# to the devices.
For now, the best approach seems to default to disabling PCI by defaulting
pciedisable=1. This can be overridden by the user if they need PCI in the
bootloader, for example:
- GW552x needing ethernet access in bootloader
- GW16082 expansion board needing a device-tree fixup for irq mapping

Ventana boards with a PCI Marvell Sky2 GigE MAC require the MAC address to

The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI
bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned
in the reverse order according to the PCI spec.
If the TI bridge is found on the Ventana PCI bus, add device-tree nodes
according to bus enumeration explicitly defining the interrupt mapping
to override the default PCI mapping in the Linux kernel. This allows
the GW16082 to work with upstream kernels that support device-tree
irq parsing.

This is useful information to show how close we are to the limit. At present
it is only available by enabling DEBUG in board_r.c.
Make it available with the 'bdinfo' command also.

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.
Signed-off-by: Simon Glass <sjg@chromium.org>
We currently use dm_scan_fdt_node() to bind devices. It is an internal
function and it requires the caller to know whether we are pre- or post-
relocation.
This requirement has become quite common in drivers, so the current function
is not ideal.
Add a new function with fewer arguments, that does not require internal
headers. This can be used directly as a post_bind() method if needed.

Disable the sun8i emac driver for now, there are 2 issues with it:
1) It is causing issues with network connectivity under the kernel driver,
when booting the kernel with v2 of Corentin's sun8i-h3 emac driver, I get
the connection status bouncing between connected at 100mbps full-duplex
and being down every second.
The second issue is that when trying to use it from u-boot
I get a number of unaligned cache flush errors:

In sun8i_emac_board_setup, the driver partially configures the syscon
register for H3 EPHY. However, the settings are incomplete, and
completely unusable. The correct settings are later set in
sun8i_emac_set_syscon, but the incorrect CLK_SEL setting persists.
It is incorrect to use CLK_SEL to select 25 MHz, as the SoC does not
have a 25 MHz clock the EPHY can use.
This patch removes the setting of the syscon register in board_setup,
and also moves set_syscon above mdio_init. While mdio_init does not
access the PHY, it is better to have the PHY parameters setup before
the MDIO bus is registered.

The sun8i_emac driver erroneously configures the AHB2 clock when it
assumes it is configuring the AXI gates, which is not even documented
or ever appeared in either the WiP kernel driver or Allwinner's original
driver.
As a result, AHB2 clock mux is set to an invalid setting, making the
EPHY unusable.

this is an extended version of the regular Orange Pi PC
with sdio wifi and an eMMC.
