The AM65x family of SoCs has two Silicon Revisions - SR1.0 and SR2.0.
The current dtsi and dts files all define the nodes to represent and/or
use the AM65x SR2.0. Add a new overlay file 'k3-am654-sr1.dts' to specify
the delta differences between the two Silicon revisions. This overlay
should be applied on top of the actual AM65x board dts files.
The AM65x SR2.0 SoCs have a revised ICSSG IP that is based off the
subsequent IP revision used on J721E SoCs. The ICSSG IP on AM65x SR2.0
SoCs have two new custom auxiliary PRU cores called Transmit PRUs
(Tx_PRUs) in addition to the existing PRUs and RTUs, but these are
not present on AM65x SR1.0 SoCs. The Tx_PRU nodes are added and enabled
by default in the base k3-am65-main.dtsi file, but these are absent on
SR1.0, so mark them disabled specifically.

Add the DT nodes for the ICSSG0, ICSSG1 and ICSSG2 processor subsystems
that are present on the K3 AM65x SoCs. The three ICSSGs are identical
to each other for the most part, with the ICSSG2 supporting slightly
enhanced features for supporting SGMII PRU Ethernet. Each ICSSG instance
is represented by a PRUSS subsystem node. These nodes are enabled by
default.

The J721E PM1 SoM uses TPS65917 PMIC, and uses a different regulator
(SMPS12) as the supply for A72 AVS Class 0. Add support for this by
fixing up the DT supply dynamically based on the board version to
get the right phandle for avs supply regulator.
The same k3-j721e-r5-common-proc-board.dts file is used to avoid
dynamic detection for R5 SPL DTB, with the TPS65917 PMIC nodes
added. Both PMIC nodes are present (not at all ideal), but their
sole usage is to provide for AVS Class 0 functionality.
There is no plan to upstream this support, and hence the simpler
HACK approach is taken.

Due to a limitation for USB DFU boot mode, SPL load address has to be less
than or equal to 0x70001000. So, load address of SPL and ATF have been
moved to 0x70000000 and 0x701a0000 respectively.
Also, the maximum size of ATF has been increased to 0x1c000 [1].
Therefore, update ATF's location and maximum size accordingly in the device

The default U-Boot environment variables and design are all set up for
both the MAIN R5FSS clusters to be in Split-mode. This is the setting
in v2021.01 U-Boot and the dt nodes are synched with the newer kernel
binding property names in commit c118d25546 ("remoteproc: k3_r5:
Sync to upstreamed kernel DT property names").
The modes for both the clusters got switched back to LockStep mode by
mistake in commit 16c0c84460 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6
dts into U-Boot"). This throws the following warning messages when
early-booting the cores using default env variables,
k3_r5f_rproc r5f@5d00000: Invalid op: Trying to start secondary core 7 in lockstep mode
Load Remote Processor 3 with data@addr=0x82000000 98484 bytes: Failed!

Load Remote Processor 5 with data@addr=0x82000000 98484 bytes: Failed!
Fix this by switching back both the clusters to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.

While Kernel expects ethernetX alias to point to individual ethernet
ports in case of multi MAC ethernet controller, U-Boot DM core expects
ethernetX alias to point to the node that ethernet (am65-cpsw-nuss)
driver binds to. Hence aliases copied from kernel DT will
leads to 3 issues:
- ethernet interfaces on K3 SoCs get a different seq number than that of
intended alias (eg.: CPSW port0 on AM65x get eth1 instead of eth0).
- "ethaddr" env variable is no longer set to eFuse MAC address.
- U-Boot FDT fixup code won't update MAC address in Kernel's DT
due to missing "ethaddr" variable.
Fix this by updating alias to point to CPSW node in -u-boot.dtsi file
for all K3 SoCs to match U-Boot's expectation.

The AM654 IDK daughter card supports few additional peripherals
like MCAN and 4 ICSSG Ethernet ports. The ICSSG IP is different
between the two AM65x Silicon Revisions SR1.0 and SR2.0, and so
warrants a separate overlay file when using on top of a AM654
base board populated with a SR1.0 silicon.
Add a new k3-am654-idk-sr1.dts overlay file, which includes the
k3-am654-idk.dts overlay file. The built overlays are identical
for now, but will diverge after ICSSG Ethernet support is added.
This fixes the following warning currently seen in A53 SPL on
AM65x EVMs with SR1.0 after the board logic is fixed up to pick
the separate overlay for kernel in commit ba961d78ac16 ("board:
