Since eMMC HS400 has been descoped for J722s due to errata i2478 [0]
and is supported for AM62Px device, remove eMMC HS400 support from

This patch adds the dt for SK-AM62-SIP, which uses the existing
SK-AM62 board design with the new AM6254atl SiP. This changes the
location of memory node from the board dts to SoC level dtsi
(k3-am6254atl in our case).
Therefore this patch introduces the new 'k3-am625-sk-common.dtsi'
which represents the common hardware used for both 'am625-sk' and
'am6254atl-sk' boards with the inheritance hierarchy modified to:
k3-am625-sk.dts:
k3-am62 k3-am62x-sk-common

The k3-am62x-sk-common dtsi represents the common hardware used across
am62x EVMs which can be configured with various DDR sizes or none (with
DDR integrated in the package) based on the specific am62x SoC used.
Therefore this patch moves the memory node and the SoC specific k3-am625
dtsi out of sk-common and into the board dts files. No functional change
is intended from this patch. The device-tree inheritance is changed as
follows:
Before:
k3-am62
^
k3-am625

k3-am62x-sk-common

am62x EVMs (k3-am625-sk, k3-am62-lp-sk)

The TI K3 AM65 SoCs have multiple programmable remote processors like
R5Fs. The TI SDKs for AM65 SoCs offer sample firmwares which could be
run on these cores to demonstrate an "echo" IPC test. Those firmware
require certain memory carveouts to be reserved from system memory,
timers to be reserved, and certain mailbox configurations for interrupt
based messaging. These configurations could be different for a different
firmware.
While DT is not meant for system configurations, at least refactor these
configurations from board level DTS into a dtsi for now. This dtsi for
TI IPC firmware is board-independent and can be applied to all boards
from the same SoC Family. This gets rid of code duplication and allows

This reverts commit 1a314099b7.
The C6x carveouts are reversed intentionally. This is due to the
requirement to keep the DMA memory region as non-cached, however the
minimum granular cache region for C6x is 16MB. So, C66x_0 marks the
entire C66x_1 16MB memory carveouts as non-cached, and uses the DMA
memory region of C66x_1 as its own, and vice-versa.
This was also called out in the original commit which introduced these
reversed carveouts:
"The minimum granularity on the Cache settings on C66x DSP
cores is 16MB, so the DMA memory regions are chosen such that
they are in separate 16MB regions for each DSP, while reserving
a total of 16 MB for each DSP and not changing the overall DSP
remoteproc carveouts."

Remote Processors defined in top-level AM65x SoC dtsi files are
incomplete without the memory carveouts and mailbox assignments which
are only known at board integration level.
Therefore, disable the remote processors at SoC level and enable them at
board level where above information is available.

The J742S2 SoC reuses the common k3-j784s4-j742s2-mcu-wakeup-common.dtsi
for its MCU domain, but it does not override the firmware-name property
for its R5F cores. This causes the wrong firmware binaries to be
referenced.
Introduce a new k3-j742s2-mcu-wakeup.dtsi file to override the
firmware-name property with correct names for J742s2.

The SERDES0 instance of SERDES on the AM69 SoC is a Cadence Torrent SERDES
and it has 4 lanes which are allocated in the following manner:
Lane0 and Lane1 to PCIe1
Lane2 to PCIe3
Lane3 to USB0
Until [0], the Cadence Torrent SERDES driver only supported configuring
the SERDES for a PCIe + USB configuration whereby all lanes of the
SERDES configured for PCIe will operate at the same speed. As a result,
PCIe1 and PCIe3 instances of PCIe will either fall down to a common
speed based on the PCIe peers that they are each connected to, or, the
PCIe link could fail to be setup.
Since [0] enables support for PCIe Multilink + USB configuration, it is
now possible for the SERDES lanes allocated to PCIe1 and PCIe3 to link up
and operate at different speeds. USB continues to remain functional.
Hence, update the 'serdes0' node as well as the 'pcie1_rc' and 'pcie3_rc'
nodes to switch to the PCIe Multilink + USB configuration that is now
supported by the Cadence Torrent SERDES driver.

Add missing address-cells 0 to the PCI interrupt node to silence W=1
warning:
k3-j721s2-main.dtsi:1431.3-1434.29: Warning (interrupt_map): /bus@100000/pcie@2910000:interrupt-map:
Missing property '#address-cells' in node /bus@100000/pcie@2910000/interrupt-controller, using 0 as fallback
Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent
component, is not used (=0)
