78b9afd2c3 am335x-evm: Enable required dtb nodes in SPL
For successful boot when CONFIG_SPL_OF_CONTROL=y, we need to ensure that
the board EEPROM on i2c0, the uart0 serial port and the relevant boot
device (mmc1 or mmc2) can be accessed in the SPL. We also need to
preserve the parent nodes for each required dtb node.

ff94c15a3c video: omap: add panel driver
The previous version of am335x-fb.c contained the functionalities of two
drivers that this patch has split. It was a video type driver that used
the same registration compatible string that now registers a panel type
driver. The proof of this is that two compatible strings were referred
to within the same driver.
There are now two drivers, each with its own compatible string,
functions and API.
Furthermore, the panel driver, in addition to decoding the display
timings, is now also able to manage the backlight.

72e0a0e1c7 arm: dts: am335x: add 'u-boot, dm-pre-reloc' to panel
Add the "u-boot,dm-pre-reloc" property to the "ti,tilcdc,panel"
compatible node. In this way the video-uclass module can allocate the
amount of memory needed to be assigned to the frame buffer.
For boards that support Linux the property is added to the *-u-boot.dtsi
file since it is a u-boot specific dt flag.

Ran building tests with CONFIG_AM335X_LCD enabled and disabled for the
following configurations:
 - brxre1_defconfig           --> success
 - am335x_guardian_defconfig  --> success
 - am335x_evm_defconfig       --> success
 - da850evm_defconfig         --> failure with CONFIG_AM335X_LCD enabled

Enabling CONFIG_AM335X_LCD in da850evm_defconfig causes building errors
even without applying the patch. The driver has never been enabled on the
da850 and must be adapted for this platform.

db34e0ede0 ARM: DTS: am335x-evm: Use USB0 in peripheral mode
This USB port is mainly used for RNDIS and DFU. To be able to use it with
DM_USB and DM_USB_GADGET, we need to provide a dr_mode value in the DTS.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

ad99abe8e7 ARM: dts: am335x-evm: disable mmc3
SDIO is not supported in u-boot, there is no point in enabling mmc3.
For this purpose, add u-boot specific dtsi that this will be included
automatically while building the dtb.
