f748ec9d32 ARM: k2g: add a workaround to reset the phy
This patch adds a workaround to reset the phy one time during boot
using GPIO0 pin 10 to make sure, the Phy latches the configuration
from the input pins correctly.

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.

c5f177debc ARM: k2g: Add support for dynamic programming of PLL based on SYSCLK
K2G supports various sysclk frequencies which can be
determined using sysboot pins. PLLs should be configured
based on this sysclock frequency. Add PLL configurations
for all supported sysclk frequencies.

e2924e5904 ARM: k2g: Configure reset mux to device reset
BOOTCFG_RSTMUX8 register controls the reset mux associated with the ARM.
Timer5(dedicated to ARM) when used as WatchDog timer, the events it
generates are routed to the above mux.

Following are the 3 events that can controlled bt the reset mux:
- Device Reset
- An interrupt to the ARM_GIC
- An interrupt to the ARM_GIC followed by a device reset.

Right now to give a default watchdog behaviour "Device reset" is
being selected.

f2a8279e76 ARM: keystone2: K2G: power-off DSP during boot
The DSPs are powered on by default upon a Power ON reset, and
they are powered off on current Keystone 2 SoCs - K2HK, K2L, K2E
during the boot in u-boot. This is not functional on K2G though.
Extend the existing DSP power-off support to the only DSP present
on K2G. Do note that the PSC clock domain module id for DSP on K2G
differs from that of previous Keystone2 SoCs.
