dbab8b8e10 mx6cuboxi: Fix boot of hummingboard dual-lite
Hummingboard dual-lite is picking the incorrect calibration structure.

Fix it so that it can boot.

While at it, also fix p1_mpdgctrl1 register to match Solid-run's
setting.

a4d450380c mx6cuboxi: Pull down PAD_ENET_RXD0/RXD1
Configure PAD_ENET_RXD0/RXD1 pads as pull down because these pads are directly
connected to the Atheros 8035/8030 although they should be functional
only in the RMII mode - 8030.

712be3eef6 mx6cuboxi: Fix Ethernet PHY detection problem
mx6cuboxi sometimes fails to recognize the Ethernet PHY:

Net:   Phy 0 not found

The explanation for this behavior comes from from Rabeeh Khoury:

"The LED_ACT pin on the carrier-one boards had a pull down that
forces the phy address to 0x0; where on CuBox-i and the production
HummingBoard that pin is connected directly to LED that depending
on the pull down strength of the LED it might be sampled as '0' or '1' thus
the phy address might appear as either address 0x0 or 0x4."

"This is AR8035 implementation; in reset stage the LED pin is configured as
input, and pull up/down does matter. In this case it configures the PHY
address.

After reset is deasserted the same LED pin becomes output and then
according to the previous pull/up it should be active high/low"

One way to properly fix this behavior is to place external pull-up/down
resistors in the LED line, but from a software standpoint we can fix it
by telling phy_find_by_mask() to scan the PHY at addresses
0x0 and 0x4.

f68a9c6b3d mx6cuboxi: Add HDMI output support
Add HDMI output using PLL5 as the source for the IPU clocks,
and accurate VESA timings.

These settings are based on the patch from Soeren Moch <smoch@web.de>
submitted for the tbs2910 mx6 based board.

It allows the display to work properly at 1024x768@60.

This should make the hdmi output signal compatible with most if not all
modern displays.

205d58699b mx6cuboxi: Load the correct 'fdtfile' variable
Instead of hardcoding the 'fdtfile' variable, let's detect the SoC and
board variant on the fly and change the dtb name.

Based on the scheme done on am335x board.

8cb6817e3a mx6cuboxi: Introduce multi-SoC support
Cubox-i and Hummingboard support several MX6 SoCs: mx6solo, mx6dual-lite,
mx6dual and mx6quad. Add support for the different SoC/memory sizes
combinations.

DDR initialization values were extracted from Solid-run internal U-boot.

Tested on a CuBox-i4Pro, HummingBoard-i2eX and HummingBoard-i1.
