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.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

So introduce a mechanism for users to be able to configure

Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

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.

UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. For backwards compatibility to not break users
who have old bootloaders and newer kernels the device-tree on boards with
microSD disables UHS-I support by default by defining the no-1-8-v property
in the esdhc controller node. For models/revisions that support switchable
1.8V/3.3V I/O which is detectable by the presence of a pull-down on the
SD3_VSELECT pin we remove that property to enable support in the kernel.

Additionally we add SD3_VSELECT to the pinmux for clarity (even though U-Boot
does not currently support UHS-I modes requiring 1.8V I/O).

Removed several EEPROM bit dependencies:
 - for dt aliases that don't exist and thus don't ever do anything
   (pcie,lvds1,uart*,vpu,csi*,hdmi_in,hdmi_out,cvbs_in,cvbs_out,gps)
 - for features that don't effect bus ordering or have no detrimental affect
   if erroneously enabled when not present (ahci,nand,i2c*)
 - for features that have little to no impact on being erroneously enabled
   but high impact if erroneously disabled (can*, spi*)
 - for features that have an high adverse affect of not being set when they
   should and no adverse affect of being set when they
   shouldn't (ipu*).

Removing these means the following:
 - these no longer are supported with the econfig command
 - these no longer affect the device-tree in any way

5c55572ff7 imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bit
The MSATA feature is a board-specific feature on Gateworks Ventana boards.

In most cases a 2:1 mux will steer either PCIe or SATA to a miniPCIe socket
through an MSATA_EN gpio. In these such cases assign the gpio in the board
specific struct and use its presence to determine if we default the GPIO to
PCIe and if we later steer it according to hwconfig.

f17a9af846 imx: ventana: enable pwm device-tree property based on hwconfig
Most Ventana boards have a connector with off-board digital-I/O signals
including some that can be pinmuxed as either a PWM or a GPIO. The hwconfig
env variable is used to configure these and they will be pinmuxed according
to this configuration in the bootloader.

This patch adds a device-tree fixup that will enable the pwm controller
nodes appropriately for digital-I/O's that are configured as pwm via hwconfig
so that the pin can be used with the Linux kernel /sys/class/pwm API.
