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.

101d2171e1 arm: am57xx: cl-som-am57x: Use new pinctrl macros
Commit 6ae4c3efbd ("ARM: DRA7: Add pinctrl register definitions")
has added new macros for pinmux configuration in line with the
kernel definitions. Fixup the current pinctrl data for the CompuLab
CL-SOM-AM57x board to use these new macros to facilitate the removal
of the old macros.

NOTE:
The PEN and PDIS macro values used previously were actually defined
inversely, a value of 1 in bit position 16 actually means that the
internal pullup/pulldown is disabled and not enabled as inferred by
PEN. So, previous pinmux config data such as (PDIS | PTU) is confusing
as it actually was meant for enabling internal pullup. The data is
fixed up only to be equivalent to the previous data.

fc300e2c5d arm: am57xx: cl-som-am57x: add ETH support
Add MAC support.

Use PHY, connected to RGMII1 as a default Eth adapter,
by appropriate setting of 'cpsw_data.active_slave'.

'cpsw_phy' env variable can override this setting.

Set the MAC addresses in the U-Boot environment.
The addresses are retrieved from the on-board EEPROM or from the SOC's
MAC fuses.

Set the following PHYs RGMII clock delays:
- Enable RX delay
- Disable TX delay
