e7356f08e9 arm: dts: k3-am642-*: Mark the memory node with u-boot, dm-spl
Since commit dffdb1f8eb ("board: ti: am64x: Use fdt functions
for ram and bank init") ddr_init() and dram_bank_init() have
switched to fdtdec for getting the memory configuration from
the am64xx dts files instead of using hardcoded values. This
requires an accessible memory node in SPL as we already have
in k3-am642-r5-evm.dts.

Make the memory node accessible in A53 SPL for both am642-sk
and am642-evm and in am642-sk R5 SPL.

a97ee92e4a arm: dts: k3-am642-evm: Add sysreset controller node
The AM64x SoC uses a central Device Management and Security Controller
(DMSC) processor that manages all the low-level device controls
including the system-wide SoC reset. The system-wide reset is managed
through the system reset driver.

Add a sysreset controller node as a child of the dmsc node to enable
the "reset" command from U-Boot prompt for the K3 AM642 EVM.

bc17fccbd0 ARM: dts: k3-am64-main: Add CPSW DT nodes
AM64 as CPSW3G IP with 2 external ports. Add DT entries for the same
(based on kernel DT).

Disable second port as its by default set to ICSS usage on EVM.
